Reason R: Rapid secretion of LH in the middle of menstrual cycle induces rupture of Graafian follicle and thereby the release of ovum. In the light of the above statements, choose the most appropriate answer from the options given below.
- A. A is correct but R is not correct.
- B. A is not correct but R is correct.
- C. Both A and R are correct and R is the correct explanation of A.
- D. Both A and R are correct but R is NOT the correct explanation of A.

During the follicular phase, rising estrogen from the developing follicle promotes repair of the endometrium. Which phase of the uterine cycle does this correspond to?
- A. Menstrual shedding only
- B. Secretory phase
- C. Proliferative phase
- D. Parturition phase
After ovulation, the corpus luteum secretes high levels of progesterone. What is one major effect?
