  • B
    three sperms
  • ✓
    two sperms and a vegetative cell
  • D
    single sperm and a vegetative cell.

Answer

Correct option: C.
two sperms and a vegetative cell
c
(c) : 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 non­motile male gametes (or sperms). Thus, the male gametophyte in angiosperms produces two sperms and a vegetative cell. The vegetative cell, later on, grows to produce pollen tube.
