Out of the following options, which is the best strategy to avoid acquiring HIV?

Correct option is D

Correct Answer: (d) Restrict sex to a single known healthy person
Explanation:
The best strategy to avoid acquiring HIV (Human Immunodeficiency Virus) is to restrict sexual activity to a single, monogamous relationship with a partner who is known to be healthy and HIV-negative. This significantly reduces the risk of exposure to the virus, as it eliminates the possibility of contact with an infected partner.
Why the other options are incorrect:
· Simply by avoiding sex with people who have AIDS: While avoiding sex with individuals who are known to have AIDS reduces the risk, it is not a sufficient strategy since individuals may be HIV-positive without showing symptoms of AIDS.
· Only avoid sex with drug addicts: This is an incomplete strategy because HIV can be transmitted through unprotected sex, regardless of whether the partner is a drug addict or not.
· Only restrict sex with prostitutes: While prostitutes may be at a higher risk of HIV exposure due to multiple partners, the best strategy is to avoid unprotected sex with anyone whose HIV status is unknown, not just sex workers.
