Solution

The correct option is B Porogamy, Syngamy, Triple fusion
  • Double fertilization is characterized by the fusion of one male gamete fuses with egg nucleus (syngamy) to form the diploid embryo and that of others with the diploid central cell (triple fusion) to form triploid primary endosperm nucleus.
  • The entry of the pollen tube in the egg apparatus through micropyle (porogamy) is followed by syngamy and triple fusion.
    So, the correct answer is option C.
