Solution

The correct option is B Endosperm formation
Free nuclear division is a mitotic division of nucleus which is not followed by cytokinesis. In angiosperms, free nuclear division occurs during endosperm formation. Hence, the endosperm is called as liquid endosperm as cell wall is not formed after mitotic division. It is seen in coconut.
Thus, the correct answer is 'Endosperm formation.'
