Solution

The correct option is B karyokinesis not followed by cytokinesis
In the most common type of endosperm development, the primary endosperm nucleus (PEN) divides successively to give rise to free nuclei. This stage of endosperm development is called free-nuclear endosperm.
In coconut, the coconut water is liquid endosperm which is formed as a result of free nuclear divisions (karyokinesis).
The free nuclear divisions are not followed by cytokinesis and hence there is no cell wall formation between the cells in liquid endosperm.
