Solution

The correct option is C $2 : 1$
Sperm is the male gamete that contains half the number of chromosomes compared to other cells in males and it is same for the female gametes as well. Male and female gamete combine to form a zygote and hence zygote has double the number of chromosomes compared to the sperms.
