The correct answer is: 2 celled stage
Pollen grains represent male gametocyte. When pollen grains mature it consists of the vegetative cell which is bigger and has ample food reserve and generative cell which is relatively smaller. In over 60% of angiosperms pollen grains are shed at this 2 celled stage and in the remaining of angiosperms generative cell undergoes mitotic division resulting in the formation of two male gametes before pollen grains are shed (3 celled stage)
