Solution

The correct option is A
Both A and R are true and R is the correct explanation to A.

In anemophily (pollination through wind) and hydrophily (pollination through water), pollen reaching the compatible stigma is totally dependent on chance. To increase the probability of successful pollination, pollen grains are produced in large numbers by these plants.
