Answer 1

The correct option is C Fusion of a male gamete with the egg and the other with two polar nuclei.

Double fertilization is a unique process that is a feature of the angiosperms, the flowering plants. In this, the pollen grains produce two sperms. One of them fuses with the egg to form a zygote and the other fuses with the polar nuclei that resembles the fertilization.
