Number of meiotic divisions necessary to produce 100 seeds in cyperus is

The correct option is C 200

For the formation of 100 seeds, 100 egg cells and 100 pollen grains are required.

The pollen mother cell produces 4 pollen grains, but 3 of them degenerate. Hence for 100 pollen grains to be formed, 100 divisions are required in Cyperus.

Total number of meiotic divisions required to produce 100 seeds in Cyperus = No. of divisions required for egg cells + No. of divisions required for pollen grains

=100+100

=200

So, the answer is B.
