The Correct Option is D
Approach Solution - 1
Emergency Contraception Mechanism: Emergency contraceptive pills (ECPs) typically contain: - High-dose progestogen (levonorgestrel) alone OR - Combined progestogen-estrogen (Yuzpe method)
These work by: 1. Delaying or inhibiting ovulation 2. Preventing fertilization 3. Possibly interfering with implantation
Thus, the correct answer is (D) Progestogen-Estrogen combination, representing the hormonal composition of emergency contraceptive pills.
