The correct option is A IUD
IUD is a method of birth control. An interuterine device is a tiny device that's inserted in your uterus to prevent pregnancy. It's long-term, reversible, and one of the most effective birth control methods. GIFT (gamete intrafallopian transfer) , ZIFT (Zygote intrafallopian transfer) and IVF (Invitro fertilization) are assisted reproductive technologies.
