(B) In over $60\%$ of angiosperms,pollen grains are shed at the $2$-celled stage.In this stage,the pollen grain consists of a vegetative cell and a generative cell.In the remaining species,the generative cell divides mitotically to give rise to two male gametes before pollen grains are shed,resulting in a $3$-celled stage.Therefore,the most common stage of pollination in angiosperms is the $2$-celled stage.
