Solution

The correct option is B Cleavage of fertilized egg
When the envelopes of the sperm and the egg pronuclei degenerate and their chromosomes intermingle to form synkaryon. This is known as syngamy. The proximal centriole helps sperm to form the spindle for the division of synkaryon (cleavage nucleus), which then immediately begins cleavage. Hence, option B is correct.
