The correct option is C two sperm cells and a vegetative cell
The protoplast of the male gametophyte divides mitotically to produce two unequal cells – a small generative cell and a large vegetative cell. The generative cell divides later into two non-motile male gametes or sperm cells. Thus, the male gametophyte in angiosperms produces two sperms and a vegetative cell. The vegetative cell, later on, grows to produce the pollen tube.
