Solution

The correct option is D Assertion is false but Reason is true
Endosperm (3n)is formed by the fusion male gamete (n) and two polar nuclei (n) and form a triploid tissue. Endosperm provides the nourishment to the developing embryo.
Trapaceae and Orchidaceae do not have endosperm.
So, the correct option is 'assertion is false but reason is true'.
