1. Development of embryo becomes abnormal
2. Abortion occurs after some time
3. Embryo develops normally till birth

Correct answer: Embryo develops normally till birth

Solution

By the fourth month, the placenta is producing enough progesterone and estrogen to maintain the pregnancy even if the ovaries are removed. Therefore, the embryo can continue developing normally until birth.
