Answer:
The correct option is B. It helps the fertilized egg attach to the uterine wall.
Explanation:
The uterus contains some of the strongest muscles of the body. It is made up of three thick layers:
1. The perimetrium 2. the myometrium and 3. the endometrium.
The walls of the endometrium thicken during ovulation and also pregnancy.
When fertilization occurs, the walls of the uterus help the eggs to stick to the uterine walls. The endometrium thickens more and more to protect the egg and to nourish it..
