Correct Answer is ["A","C","D"]
Explanation
Choice A rationale
Ethinyl estradiol and drospirenone (Yaz) is a combination oral contraceptive used to prevent pregnancy. It works by inhibiting ovulation, altering the cervical mucus to prevent sperm penetration, and changing the uterine lining to prevent implantation.
Choice B rationale
Finasteride is not used for contraception or prevention of pregnancy. It is primarily used to treat benign prostatic hyperplasia (BPH) and androgenetic alopecia (male pattern baldness).
Choice C rationale
Desogestrel (Mirena) is a hormonal intrauterine device (IUD) used for long-term contraception. It releases a progestin hormone that thickens cervical mucus, inhibits sperm motility, and thins the endometrial lining to prevent pregnancy.
Choice D rationale
Medroxyprogesterone acetate (Depo-Provera) is an injectable contraceptive that provides long-term prevention of pregnancy. It prevents ovulation and thickens cervical mucus to inhibit sperm penetration.
