Disinfectants are specifically formulated chemical agents designed to eliminate or reduce harmful microorganisms on inanimate surfaces. They are effective against a broad range of pathogens, including bacteria and viruses. The correct choice indicates that disinfectants are generally not considered safe for application on skin.
