Question

Match the following phases of menstrual cycle with their characteristic events: 

List-I		List-II
(A)	\(\text{Menstrual phase}\)	(I)	\(\text{Ovulation occurs}\)
(B)	\(\text{Follicular phase}\)	(II)	\(\text{Breakdown of endometrium}\)
(C)	\(\text{Ovulatory phase}\)	(III)	\(\text{Corpus luteum formation}\)
(D)	\(\text{Luteal phase}\)	(IV)	\(\text{Follicular growth}\)

Choose the correct answer from the options given below:

• A. A-II, B-IV, C-I, D-III
• B. A-I, B-II, C-IV, D-III
• C. A-II, B-I, C-IV, D-III
• D. A-III, B-IV, C-I, D-II

Hint:

Remember:

• Menstrual phase \(\rightarrow\) Endometrial shedding
• Follicular phase \(\rightarrow\) Follicle growth
• Ovulation \(\rightarrow\) Release of ovum
• Luteal phase \(\rightarrow\) Corpus luteum

Answer 1

The Correct Option is A

Step 1: Identify menstrual phase. During menstrual phase: \[ \text{Endometrium breaks down} \] Thus: \[ A \rightarrow II \]

Step 2: Identify follicular phase. During follicular phase: \[ \text{Ovarian follicles grow} \] Thus: \[ B \rightarrow IV \]

Step 3: Identify ovulatory and luteal phases. Ovulatory phase: \[ \text{Ovulation occurs} \] Luteal phase: \[ \text{Corpus luteum forms} \] Thus: \[ C \rightarrow I \] \[ D \rightarrow III \] Therefore: \[ \boxed{A-II,\ B-IV,\ C-I,\ D-III} \]
