(C) In angiosperms, the pollen grain represents the male gametophyte. During its development, the microspore undergoes mitosis to form two cells: a large vegetative cell and a small generative cell. In about $60\%$ of angiosperms, pollen grains are shed at this $2$-celled stage. In the remaining species, the generative cell divides mitotically to give rise to the two male gametes before pollen grains are shed, resulting in a $3$-celled stage. However, the mature male gametophyte in angiosperms is generally considered to be $3$-celled at the time of fertilization, consisting of one vegetative cell and two male gametes.

In angiosperms, the male gametophyte is reduced to how many cells?
