Final answer:
Contraceptive implants (option C) are an example of long-acting reversible contraception (LARC) as they are effective for up to three years and fertility is restored after their removal.
Step-by-step explanation:
Long-Acting Reversible Contraception (LARC)
The option that represents a form of long-acting reversible contraception (LARC) among those listed is contraceptive implants (option C). Contraceptive implants, such as the one marketed under the brand name Implanon, consist of a matchstick-size, flexible rod that is inserted under the skin of the upper arm. This implantable device releases a progestin hormone to create changes in the cervical mucus and uterine lining, which prevents sperm from reaching an egg, and sometimes inhibits the ovaries from releasing eggs. This method is effective for up to three years, making it long-acting. It is also reversible, as fertility is typically restored after the removal of the implant.
Other options listed, such as birth control pills and progesterone injections, are also hormonal methods but not considered long-acting. Progesterone injections, such as Depo-Provera, are given every three months, which makes them less long-acting than the implant. Birth control pills must be taken daily and are therefore not classified as long-acting. Condoms are a barrier method and not a LARC because they are used per intercourse event and have no long-term contraceptive effect.
