Solution
The correct option is A Progesterone
Progesterone is the steroid hormone, that is involved in the menstrual cycle, pregnancy and embryogenesis of humans and other species. Progesterone levels are low during pre-ovulatory phase of menstrual cycle. The levels then rise during ovulation and are elevated during luteal phase. If fertilization occurs, hCG is released, which maintains the corpus luteum and also it allows the corpus luteum to maintain levels of progesterone. So, progesterone is the pregnancy hormone. If fertilization does not occur, then progesterone levels decline drastically and menstruation takes place.Thus, the correct answer is B.
