it stops the release of eggs from the ovaries.
it restricts the movement of sperm.
it destroys the fertilized egg.

Explanation:

Mechanism of emergency contraception

Using the Contraceptives knowledge point
Emergency contraception primarily works by preventing or delaying ovulation. By stopping the release of an egg from the ovaries, there is no egg available to be fertilized by sperm, which significantly reduces the risk of pregnancy.

Evaluate the options

• Option 1: "It stops the release of eggs from the ovaries." This matches the primary mechanism of action (preventing ovulation).
• Option 2: "It restricts the movement of sperm." While some daily hormonal contraceptives can thicken cervical mucus to hinder sperm, this is not the primary mechanism of emergency contraceptive pills.
• Option 3: "It destroys the fertilized egg." Emergency contraception does not destroy an already fertilized egg or disrupt an established pregnancy; it is not an abortifacient.

Answer:

• It stops the release of eggs from the ovaries. (Correct answer)
• It restricts the movement of sperm.
• It destroys the fertilized egg.
