Please answer the following question: Information: - Wheat ("Triticum" spp., most commonly "T. aestivum") is a cereal grain (botanically, a type of fruit called a caryopsis), originally from the Levant region but now cultivated worldwide. In 2016, world production of wheat was 749 million tonnes, making it the second most-produced cereal after maize (1.03 billion tonnes), with more than rice (499 million tonnes). Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st Century. - 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. - Endosperm is a tissue produced inside the seeds of most of the flowering plants following fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. This can make endosperm a source of nutrition in the human diet. For example, wheat endosperm is ground into flour for bread (the rest of the grain is included as well in whole wheat flour), while barley endosperm is the main source of sugars for beer production. Other examples of endosperm that forms the bulk of the edible portion are coconut "meat" and coconut "water", and corn. Some plants, such as orchids, lack endosperm in their seeds. - Coconut water is the clear liquid inside young green coconuts ( fruits of the coconut palm ) . In early development , it serves as a suspension for the endosperm of the coconut during the nuclear phase of development . As growth continues , the endosperm matures into its cellular phase and deposits into the rind of the coconut meat . Given the information above, choose from the list below the object entity that exhibits the relation 'natural product of taxon' with the subject 'coconut water'. Choices: - cocos nucifera - triticum
A:
cocos nucifera
