उत्तर
A male gamete and two polar nuclei.
Explanation:
In flowering plants, during double fertilisation, one male gamete fuses with the female gamete (egg) to form the zygote, while the other male gamete fuses with the two polar nuclei in the central cell of the embryo sac to form the primary endosperm nucleus.
