How many meiosis division are essential for the formation of $100$ zygotes in human?

The correct option is C $125$
For the formation of 1 zygote in human, there must be a fusion of a haploid male and female gamete. In males, 1 meiotic division forms 4 male gametes. Hence, total 25 meiotic divisions are essential to form 100 male gametes. Similarly, in females, 1 meiotic division forms 1 female gamete. Hence, total 100 meiotic divisions are essential to form 100 female gametes. Hence, total 125 meiotic divisions are essential for the formation of 100 zygotes in human.

Thus, the correct answer is '125.'
