In some organisms, karyokinesis is not followed by cytokinesis as a result of which, multinucleate condition arises leading to the formation of syncytium. The perfect example for this is

The correct option is B Liquid endosperm in coconut

It is commonly called as liquid endosperm. Milky water in coconut is the liquid endosperm present in it. Its function is to provide nourishment for the developing embryo.

Thus, the correct answer is option B.
