Liquid endosperm in coconut is formed as a result of

The correct option is D. karyokinesis not followed by cytokinesis

Endosperm is the nutritive tissue in plants that helps in the nourishment of developing embryos.

In coconut, there is a liquid endosperm, which is formed as a result of free nuclear divisions or karyokinesis. The free nuclear divisions are not followed by cytokinesis and hence there is no cell wall formation between the cells and only presence of multiple nuclei. Hence a liquid endosperm develops due to the absence of plant cells containing cell walls.
