From the chapter: Sexual Reproduction in Flowering Plants — the Flower, Double Fertilisation and the Seed

In double fertilisation, the triploid primary endosperm nucleus is formed by the fusion of one male gamete with:

Show the answer and why

Answer: A.

One sperm fuses with the two polar nuclei of the central cell, giving a 3n primary endosperm nucleus (triple fusion). The other sperm fuses with the egg to make the 2n zygote, so choosing the egg here describes syngamy, not the endosperm-forming fusion.
