Question

which is the most effective std preventative measure?
○ spermicide
○ male condom
○ abstinence
○ hormone patch

Explanation:

To determine the most effective STD preventive measure, we analyze each option: spermicide primarily targets sperm and has limited STD prevention; male condoms reduce risk but aren't 100% effective; abstinence (not engaging in sexual activity) eliminates the risk of contracting STDs through sexual contact; hormone patches are for birth control, not STD prevention. So abstinence is the most effective.

Answer:

C. abstinence
