Question

which is a benefit of condoms as a contraceptive?
they are easy to use and rarely break or slip.
they stop ovulation from occurring.
they are more affordable than other methods.
they help to prevent allergic reactions.

Explanation:

Condoms are designed for straightforward application, and modern manufacturing reduces breakage/slippage risks when used correctly, making this a key benefit. Other options are incorrect: condoms do not stop ovulation (hormonal methods do), affordability varies by method, and they may cause allergic reactions in some users (e.g., latex allergies).

Answer:

They are easy to use and rarely break or slip.
