Solution

The correct option is B primary endosperm nucleus
The two polar nuclei present in the central cell of embryo sac fuse with the male gamete to form a primary endosperm nucleus (PEN).

Zygote is formed by the fusion of the egg cell and another male gamete.
Polar nuclei are not involved in the formation of the zygote.
