Solution
The correct option is B IUD
Physical barriers preventing pregnancy are physical barriers between the sperm and the egg. Examples of these include the male condom, female condom, diaphragm, cervical cap, and sponge. IUDs are intrauterine devices. An IUD is a tiny device that is inserted in your uterus to prevent pregnancy. It is a long-term, reversible, and one of the most effective birth control methods. However it is not a physical barrier between egg and the sperm. IUDs primarily work by preventing fertilization. The progestogen released from the hormonal IUDs may prevent ovulation from occurring but only partially. Primarily the hormone thickens the cervical mucus so that sperm cannot reach the fallopian tubes, thus acting as a mechanical contraceptive, but not a physical barrier.
