A. 200

B. 250

C. 300

D. 100

Answer: Option B

Solution(By Examveda Team)

250 pollen mother cells will form 1000 pollen grains.
One diploid microspore mother cells by meiosis form 4 tetrads of haploid microspores which become 4 pollen grains.
Thus, 250 pollen mother cells will produce 1000 pollen grains, by undergoing 50 rounds of meiosis.
