You will be given a definition of a task first, then some input of the task.
In this task, you are given a context, a subject, a relation, and many options. Based on the context, from the options select the object entity that has the given relation with the subject. Answer with text (not indexes).

Context: Moschops (Greek for "calf face") is an extinct genus of therapsid that lived in the Guadalupian epoch, around 265260 million years ago. Therapsids are synapsids, which were at one time the dominant land animals. Its remains were found in the Karoo region of South Africa., A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus., Synapsids (Greek, 'fused arch'), synonymous with theropsids (Greek, 'beast-face'), are a group of animals that includes mammals and every animal more closely related to mammals than to other living amniotes. They are easily separated from other amniotes by having a temporal fenestra, an opening low in the skull roof behind each eye, leaving a bony arch beneath each; this accounts for their name. Primitive synapsids are usually called pelycosaurs or pelycosaur-grade synapsids; more advanced mammal-like ones, therapsids. The non-mammalian members are described as mammal-like reptiles in classical systematics; they can also be called stem mammals or proto-mammals. Synapsids evolved from basal amniotes and are one of the two major groups of the later amniotes; the other is the sauropsids, a group that includes modern reptiles and birds. The distinctive temporal fenestra developed in the ancestral synapsid about 312 million years ago, during the Late Carboniferous period., Titanosuchus ferox ("Fierce Titan crocodile") was a dinocephalian therapsid that lived in the Mid Permian epoch in South Africa., South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded on the south by of coastline of Southern Africa stretching along the South Atlantic and Indian Oceans, on the north by the neighbouring countries of Namibia, Botswana and Zimbabwe, and on the east and northeast by Mozambique and Swaziland, and surrounding the kingdom of Lesotho. South Africa is the 25th-largest country in the world by land area, and with close to 56 million people, is the world's 24th-most populous nation. It is the southernmost country on the mainland of the Old World or the Eastern Hemisphere. It is the only country that borders both the Atlantic Ocean and the Indian Ocean. About 80 percent of South Africans are of Sub-Saharan African ancestry, divided among a variety of ethnic groups speaking different Bantu languages, nine of which have official status. The remaining population consists of Africa's largest communities of European (white), Asian (Indian), and multiracial (coloured) ancestry., Titanosuchids are related to other dinocephalians , such as the tapinocephalidae - a group that includes Moschops . The most famous titanosuchids are Jonkeria and Titanosuchus ., The Tapinocephalus Assemblage Zone is a geological stratum and is the thickest faunal zone of the Beaufort Group, South Africa, in which has been found a rich variety of early therapsids. The name refers to "Tapinocephalus", a genus of large herbivorous dinocephalian therapsids that lived during the Middle Permian Period., Therapsida is a group of synapsids that includes mammals and their ancestors. Many of the traits today seen as unique to mammals had their origin within early therapsids, including having their four limbs extend vertically beneath the body, as opposed to the sprawling posture of other reptiles. The earliest fossil attributed to Therapsida is "Tetraceratops insignis" from the Lower Permian. , The Beaufort Group is the third of the main subdivisions of the Karoo Supergroup of geological strata in Southern Africa. It follows conformably after the Ecca Group and consists essentially of sandstones and shales, deposited in the Karoo Basin from the Middle Permian to the early part of the Middle Triassic periods., Dinocephalia is a clade of large-bodied early therapsids that flourished for a brief time in the Middle Permian between 272 and 260 million years ago (Ma), but became extinct leaving no descendants. Dinocephalians included both herbivorous and carnivorous forms. Many species had thickened skulls with many knobs and bony projections. Dinocephalian fossils are known from Russia, China, Brazil, South Africa, and Zimbabwe., Jonkeria was a very large omnivorous (although there is some dispute to this - e.g. Colbert 1969 p. 136) dinocephalian, from the Tapinocephalus Assemblage Zone, Lower Beaufort Group, of the South African Karroo. , Subject: titanosuchidae, Relation: taxon_rank, Options: (A) family (B) genus (C) group (D) kingdom (E) species (F) variety
