Verified by Toppr

In flowering plants (angiosperms), meiotic divisions are responsible for gamete formation. Pollen mother cell undergo meiotic division to produce 4 pollen grains. So, for generation of 100 pollen grains, 100/4 = 25 pollen mother cells are required.
So, the correct answer is option A.
