Column I: i. Menstrual phase; ii. Follicular phase; iii. Ovulatory phase; iv. Secretory phase
Column II: a. Rapid secretion of LH; b. Development of primary follicle; c. Secretion of inhibin; d. Secretion of estrogen
Choose the correct option

• A. i - a, ii - b, iii - d, iv - c
• B. i - b, ii - d, iii - a, iv - c
• C. i - c, ii - d, iii - b, iv - a
• D. i - d, ii - c, iii - b, iv - a

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
The cycle has menstrual, follicular, ovulatory and secretory (luteal) phases.

Step 2: Match
Ovulatory phase goes with the rapid LH surge (a).
Secretory phase goes with secretion of inhibin by the corpus luteum (c).
Follicular phase goes with estrogen secretion (d).
Menstrual phase goes with the start of primary follicle development (b).

Step 3: Select the Option
The set i-b, ii-d, iii-a, iv-c is option B.

Final Answer:
The matching is i-b, ii-d, iii-a, iv-c. \[ \boxed{\text{(B) }\text{i - b, ii - d, iii - a, iv - c}} \]
