Question

select the correct answer.
how does emergency contraception reduce the risk of pregnancy?
a. it stops the release of eggs from the ovaries.
b. it improves the movement of sperm.
c. it destroys the fertilized egg.

Explanation:

Emergency contraception (like certain pills) works by preventing ovulation (release of egg from ovary) in many cases. Option B is wrong as it doesn't improve sperm movement (it's a contraceptive, not for aiding sperm). Option C is wrong as it doesn't destroy a fertilized egg; its main mechanism is preventing ovulation or fertilization, not acting on a fertilized egg. So A is correct.

Answer:

A. It stops the release of eggs from the ovaries.
