B) condom
C) minipill
D) vaginal ring

Accepted Answer

The vaginal ring is the most effective form of contraception, with a failure rate of only 0.3%. It contains both estrogen and progestin, which prevent ovulation and thicken cervical mucus to prevent sperm from reaching an egg. It is also convenient as it only needs to be inserted once a month.
