D Correct answer
Explanation

In menstrual cycle, estrogen causes eggs to mature and thickens the lining of the womb. In menstrual cycle, progesterone thickens the womb lining to prepare for implantation of an embryo (fertilized egg). Bleeding occurs after estrogen and progesterone levels decrease at the end of the previous cycle. This decrease causes the top layers of thickened lining of the uterus (endometrium) to break down and be shed.
