Answer 2

Emergency contraception reduce the risk of pregnancy by stops the release of eggs from the ovaries, hence option A is correct.

Emergency contraceptives do not cause an abortion, but they do prevent or delay ovulation, which prevents pregnancy. By preventing sperm from fertilizing the egg, the copper-coated IUD prevents conception. The implantation of a fertilized egg in the uterus may also be hampered.

Similar effects are produced by a progestin-coated IUD, which likewise thickens cervical mucus and thins the uterine lining. The copper-containing IUD stops fertilization by altering the chemical composition of the sperm and egg before they come into contact.
