Solution

The correct option is C Similar
Sperms and eggs are special cells, called as gametes. They have nuclei containing half the normal number of genes. For example, if the cell has total 46 chromosomes, then the nuclei of the gamete contains 23 chromosomes. During fusion, the nuclei will have the same number of chromosome as in the gamete.
So, the correct answer is option C.
