Solution

The correct option is D Estrogen and Progesterone
Estrogen and Progesterone are the two main hormones secreted by ovary which take part in menstrual cycle and pregnancy. During pregnancy, these hormones prevent the ovary from releasing an egg, thicken the cervical mucus and making it difficult for the sperm to reach the egg and change the lining of the uterus and making implantation difficult.
