Disinfectants are primarily utilized for removing or killing pathogenic microorganisms, making option B the correct choice. The primary purpose of disinfectants is to reduce the presence of harmful bacteria, viruses, and other pathogens on surfaces, thereby preventing the spread of infections, especially in healthcare settings.

Disinfectants work by employing chemical agents capable of destroying or inhibiting the growth of these microorganisms. This is crucial in maintaining a safe and sterile environment in clinical practices, where the risk of infection is heightened due to the nature of procedures performed.

Other options do not accurately reflect the primary purpose of disinfectants. For example, while cleansing surfaces for cosmetic reasons might involve cleaning agents, it does not address the microbial focus of disinfectants. Enhancing air quality relates more to air purifiers and ventilation rather than surfaces where disinfectants are applied. Promoting wound healing is a function associated with antiseptics rather than disinfectants, as antiseptics are used on living tissue to reduce the risk of infection.
