Solution

The correct option is B Progesterone
Progesterone is a hormone that regulates the monthly menstrual cycle. Progesterone is essential for the maintenance of the endometrium. Menstruation only occurs if the released ovum is not fertilized and consequently, there is a fall in blood progesterone level. This causes disintegration of the endometrium leading to menstruation.
