Given the question: Information:  - 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.  - SEED is a block cipher developed by the Korea Information Security Agency (KISA). It is used broadly throughout South Korean industry, but seldom found elsewhere. It gained popularity in Korea because 40-bit encryption was not considered strong enough, so the Korea Information Security Agency developed its own standard. However, this decision has historically limited the competition of web browsers in Korea, as no major SSL libraries or web browsers supported the SEED algorithm, requiring users to use an ActiveX control in Internet Explorer for secure web sites.  - In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin; and mesocarp, or flesh) surrounds a shell (the pit, stone, or pyrene) of hardened endocarp with a seed (kernel) inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, "lignified" stone (or pit) is derived from the ovary wall of the flowerin an aggregate fruit composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet and may together form a botanic berry.  - Pan de coco , literally `` coconut bread '' in Spanish , is a rich sweet roll with a coconut filling .  - In botany, a fruit is the seed-bearing structure in flowering plants (also known as angiosperms) formed from the ovary after flowering.  - The Arecaceae are a botanical family of perennial climbers, shrubs, acaules and trees commonly known as palm trees (owing to historical usage, the family is alternatively called Palmae). They are flowering plants, a family in the monocot order Arecales. Currently 181 genera with around 2600 species are known, most of them restricted to tropical, subtropical, and warm temperate climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts.  - The coconut tree ("Cocos nucifera") is a member of the family Arecaceae (palm family) and the only species of the genus "Cocos". The term coconut can refer to the whole coconut palm or the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from the 16th-century Portuguese and Spanish word "coco" meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.    What object entity has the relation of 'has part' with the subject 'pan de coco'?   Choices: - a  - algorithm  - berry  - coconut  - cocos nucifera  - evergreen  - flower  - fruit  - head  - information security  - order  - restricted  - spanish  - tree  - wall
The answer is:
cocos nucifera
