Solution

The correct option is D Implantation
The fixing of the blastocyst in the wall of the uterus is known as implantation. The implantation takes place after seven days of fertilization.
Placentation is the formation of placenta which links the foetus to the mother and is very essential for the growth of the foetus.
The fertilization or impregnation is the fusion of the male and female gamete to form the zygote.
So, the correct option is 'Implantation'.
