Question

Find out the incorrect match:

• A. Menstrual phase – Lasts for 3–5 days
• B. Follicular phase – LH and FSH secretion gradually decreases
• C. Ovulatory phase – LH surge
• D. Luteal phase – Graafian follicle transforms as corpus luteum

Hint:

LH surge is the key trigger for ovulation.

Answer 1

The Correct Option is B

Step 1: Understand menstrual cycle phases.
The menstrual cycle consists of menstrual, follicular, ovulatory, and luteal phases regulated by hormones.

Step 2: Evaluate option (1).
Menstrual phase lasts about 3–5 days due to shedding of uterine lining. Hence correct.

Step 3: Evaluate option (2).
During follicular phase, FSH and LH actually increase to stimulate follicle development, not decrease. Hence incorrect.

Step 4: Evaluate option (3).
Ovulation occurs due to LH surge, which triggers release of ovum. Hence correct.

Step 5: Evaluate option (4).
After ovulation, Graafian follicle transforms into corpus luteum in luteal phase. Hence correct.

Step 6: Conclusion.
Thus option (2) is incorrect.
