Assertion :In Cocos nucifera, coconut water represents the cellular endosperm and the surrounding white kernel represents the free-nuclear endosperm. Reason: Endosperm is always completely consumed by developing embryo before seed maturation.

The correct option is D Both Assertion and Reason are incorrect
In Cocos nucifera(coconut), the coconut water represents free-nuclear endosperm and the surrounding kernel represents the cellular endosperm. Endosperm may either be completely consumer by the developing embryo(e.g., pea, groundnut, beans) before seed maturation or it may persist in mature seed(e.g., castor, coconut) and is used during seed germination.
