As we have learnt- 

  • After entering one of the synergids, the pollen tube releases the two male gametes into the cytoplasm of the synergid. 
  • One of the male gametes moves towards the egg cell and fuses with its nucleus thus completing the syngamy. 
  • The other male gamete moves towards the two polar nuclei located in the central cell and fuses with them to produce a triploid primary endosperm nucleus (PEN).

Hence, the correct answer is option d.
