Answer : 4. "endosperm"
Explanation :
the edible part of a coconut is the endosperm. The endosperm is the inner, white, and fleshy part of the coconut seed, which is commonly consumed as food. It is often grated, dried, and used in various culinary applications or processed to extract coconut milk and oil. Coconut water, found inside young green coconuts, is also consumed as a refreshing beverage and is distinct from the endosperm.
