• B. 14${}^{th}$ - 16${}^{th}$
• C. Last 2 days of the menstrual cycle
• D. 8${}^{th}$ - 10${}^{th}$

Answer 1

The correct option is B 14${}^{th}$ - 16${}^{th}$

During menstruation cycle, gonadotropins (LH and FSH) stimulates follicular development as well as secretion of estrogens by the growing follicles. Both LH and FSH reached at maximum level in the middle of the cycle (about 14${}^{th}$ day). Rapid secretion of LH leads to LH surge and rupture the Graafian follicle for ovulation to occur.

Thus, the correct answer is option B.
