Select the correct sequence of menstrual cycle.
1 Menstruation, Secretory, Follicular, New cycle.
2 Menstruation, Follicular, Luteal, New cycle.
3 Follicular, Menstruation, Luteal, New cycle.
4 Luteal, Menstruation, Follicular, New cycle.
Explanation:
(b) The cycle starts with the menstrual phase. When menstrual flow occurs, it lasts for $3-5$ days. The menstrual phase is followed by the follicular phase or proliferative phase. The luteal or secretory phase just follows the former and completes the cycle. Then, all new cycle begins thereafter.

4 Both LH and FSH attain a peak-level in the middle of cycle.
Explanation:
(d) Menstrual cycle is the cycle of natural changes that occurs in the uterus and ovary as an essential part of making sexual reproduction possible. Menstrual fluid cannot easily clot. The end of the cycle of menstruation is called menopause. During the follicular phase, gonadotropins (LH and FSH) increase gradually and stimulate follicular development as well as secretion of estrogen by growing follicles.
