Verified by Experts

The correct Answer is:
d
In Cocos nucifera (coconut), the coconut water represents free-nuclear endosperm and the surrounding kernel represents the cellular endosperm. Endosperm may either be completely consumed by the developing embryo (e.g., peas, groundnut, beans) before seed maturation or it may persist in mature seed (e.g., castor, coconut) and is used during seed germination.
