Solution

The correct option is B one male gamete fuses with the egg and the other fuses with the secondary nucleus
Double fertilisation
  • The pollen grain consists of two male gametes.
  • Out of these two, one fuses with the female gamete (syngamy), whereas the other fuses with the polar nuclei (triple fusion).
  • Both syngamy and triple fusion together is called double fertilisation.
