Answer 1

The correct option is B

Fusion of nuclei of male and female gamete

The correct option is B.

Explanation for the correct option:

1. The haploid nucleus of the sperm and that of the ovum fuse during fertilization to form the zygote.
2. Then the zygote divides into embryos, which develop into the fetus.

Option C:

1. Adhesion of male and female reproductive organs is known as mating.

Option D:
