What is the only method 100% effective in preventing both pregnancy and sexually transmitted infections?

Explanation:
The concept is that complete avoidance of vaginal sexual activity eliminates any exposure that could lead to pregnancy or STI transmission. Abstinence achieves this by not engaging in vaginal sex at all, so there is no opportunity for conception or infection. Other methods reduce risk but do not eliminate it. A condom lowers the chance of both pregnancy and many STIs but isn’t 100% effective due to factors like incorrect use or breakage, and some infections can be spread through skin-to-skin contact in areas not covered by a condom. An IUD prevents pregnancy but offers no protection against STIs. Withdrawal lowers pregnancy risk but does not safeguard against STIs.
