A. It prevents HIV patients from catching airborne diseases.

Explanation:

HIV targets the helper T cells of the immune system and weakens the immune responses of the patient. The patients are more susceptible to get secondary infections. Wearing masks do not allow these patients to get infected with any airborne diseases due to their compromised immune system. HIV is spread through body fluids only and can not be transmitted with air.
