Verified step by step guidance

Understand the primary function of each birth control method listed: Diaphragms, Condoms, Oral Contraceptives, and IUDs.

Recognize that sexually transmitted infections (STIs) are primarily transmitted through direct contact with infected bodily fluids or skin.

Identify which birth control methods provide a physical barrier to prevent the exchange of bodily fluids, which is crucial in preventing STIs.

Note that condoms are the most effective method among those listed for preventing STIs because they provide a physical barrier.

Understand that oral contraceptives, while effective for preventing pregnancy, do not provide any barrier against STIs, making them the least effective method for STI prevention.
