Answer:

B) restores the diploid number of chromosomes.

Explanation:

A pronuclei is the nucleus of a male (sperm) or female (egg cell) reproductive cell during fertilization (fusion of gametes). These pronuclei possess the genetic material that will eventually fuse when their membranes dissolve, <em>their chromosomes then combine and become an embryo with a diploid nucleus that will contain a full set of chromosomes (23+23=46 chromosomes.)</em>

I hope you find this information useful and interesting! Good luck!
