Disinfection is correctly defined as the process that involves the killing of pathogenic microorganisms, but it does not eliminate all microbial life, especially bacterial spores. This definition captures the goal of disinfection, which is to reduce the number of viable pathogens on surfaces or instruments to a level that is not harmful to health.

In healthcare and central service settings, achieving a balance between eliminating pathogens and preserving the integrity of instruments is crucial. Disinfectants are often used on equipment and surfaces that may come into contact with patients or sterile supplies. Standard disinfection methods can vary in their effectiveness depending on factors such as the type of disinfectant used, the concentration, the contact time, and the presence of organic matter.

In contrast, complete destruction of all forms of microbial life describes sterilization, not disinfection. The use of physical barriers to prevent contamination typically refers to aseptic technique or practices rather than disinfection. Cleaning with soap and water is a preliminary step in the decontamination process, but it is not a method of disinfection on its own. Thus, option B clearly aligns with the accepted definition of disinfection in the context of infection control and sterilization practices.
