Answer: 1. Lactational amenorrhea, Pills, Emergency contraceptives

Key idea: Only methods that change hormone levels involve a hormone.

Oral pills: progestogen-oestrogen combinations stop ovulation.
Emergency contraceptives: high-dose progestogen or progestogen-oestrogen.
Lactational amenorrhea: high prolactin during lactation suppresses ovulation (hormonal basis).

Barrier methods (condom, diaphragm) and CuT (copper ions affect sperm motility) are not hormone based, which rules out options 2, 3 and 4.
