Which of the following is an example of antifertility drug?
Show Hint
Antifertility drugs are typically hormonal (progestins/estrogens). Distinguish from antiseptics (bithionol), sweeteners (sucralose), or fragrances (terpineol). Check drug classifications.
1. Antifertility drugs are used in birth control to prevent pregnancy, often steroids like norethindrone.
2. Novestrol (norgestrel) is a synthetic progestin used in contraceptives, correct.
3. Bithionol is an antiseptic; sucralose is a sweetener; terpineol is a fragrance compound, none are antifertility drugs.
4. Thus, the answer is (3) Novestrol.
