• A. 7
• B. 14
• C. 21
• D. 28

Answer: (B)

Midcycle ovulation occurs around the midpoint of a typical 28-day cycle, about day 14. The cycle starts with the first day of menstrual bleeding, then roughly two weeks of follicular development precede ovulation. The surge in luteinizing hormone triggers release of the egg, usually about 24–36 hours after the LH peak. After ovulation, the luteal phase lasts about 14 days, ending with menstruation if fertilization hasn’t occurred. Because the total cycle is about 28 days, ovulation commonly falls near the middle, around day 14. Variations exist, but 14 is the usual reference point for a standard cycle.
