• A. P-(i), Q-(iii), R-(iv), S-(ii)
• B. P-(iii), Q-(ii), R-(iv), S-(i)
• C. P-(iii), Q-(i), R-(iv), S-(ii)
• D. P-(iii), Q-(i), R-(ii), S-(iv)

Hint:

Contraceptives are classified as natural, barrier, IUD, and hormonal methods based on mechanism.

Answer 1

The Correct Option is C

Concept: Contraceptive methods are classified into natural, barrier, intrauterine devices (IUDs), and hormonal methods. Each method works through a different biological mechanism to prevent fertilization or implantation.

Step 1: Understand Lippes loop.
Lippes loop is a non-medicated intrauterine device that prevents implantation by creating a foreign body reaction in the uterus.

Step 2: Understand Vaults.
Vaults are barrier contraceptive devices that physically prevent sperm from entering the female reproductive tract.

Step 3: Understand periodic abstinence.
This is a natural method where intercourse is avoided during the fertile period of the menstrual cycle to prevent fertilization.

Step 4: Understand Progestasert.
Progestasert is a hormone-releasing IUD that releases progesterone to prevent ovulation and implantation. Final Conclusion: Correct matching is P-(iii), Q-(i), R-(iv), S-(ii).
