Among the given options, the use of condoms is a method of prevention from HIV infection.

Using condoms correctly and consistently during sexual activity significantly reduces the risk of HIV transmission. Intra-uterine devices (like Copper-T) are contraceptives and do not prevent HIV or other sexually transmitted infections (STIs). Staying away from an HIV-infected person is not necessary for prevention as HIV is not transmitted through casual contact. Using a face mask is irrelevant as HIV is not an airborne virus.

Other effective methods for preventing HIV transmission include abstinence, reducing the number of sexual partners, consistent and correct use of condoms, pre-exposure prophylaxis (PrEP), post-exposure prophylaxis (PEP), using sterile needles for injection, and safe blood transfusion practices. Antiretroviral therapy (ART) can also reduce the viral load in infected individuals to undetectable levels, effectively preventing sexual transmission (Undetectable = Untransmittable, U=U).
