Answer:

Correct Answer: C

Solution:

*- Lactational amenorrhea: This method relies on the natural postpartum infertility that occurs when a woman is breastfeeding. The high levels of prolactin hormone during breastfeeding suppress ovulation.

• Pills: These are oral contraceptives that contain hormones (either a combination of estrogen and progestin or progestin alone) to prevent ovulation.
• Emergency contraceptives: These often contain higher doses of hormones (like levonorgestrel) to prevent pregnancy after unprotected sex.

The other options include methods that do not involve hormones:

• CuT (Copper T): This is an intrauterine device (IUD) that works primarily by releasing copper ions, which are toxic to sperm.
• Barrier methods: These include condoms, diaphragms, etc., which physically prevent sperm from reaching the egg and do not involve hormones.
