Solution

The correct option is A Amphimixis
Amphimixis is the sexual reproduction that involves the fusion of the male and female gametes. The egg nucleus, once it is haploid is known as the female pronucleus. Once the sperm enters the egg, the sperm nucleus decondenses and forms the male pronucleus. These two pronuclei then undergo fusion and zygote is formed.
So, the correct option is 'Amphimixis'.
