Antiseptics are substances that inhibit the growth of microorganisms on living tissues, and all the options listed are known for their antiseptic properties.

Alcohol is commonly used as an antiseptic for skin disinfection before surgical procedures or injections. It works effectively to kill bacteria and some viruses by denaturing proteins and disrupting cell membranes.

Hydrogen peroxide is another antiseptic that is often used for cleaning wounds. It releases oxygen when it comes into contact with tissues, creating an environment that is hostile to anaerobic bacteria, thereby helping to prevent infection.

Chlorhexidine is frequently used in surgical hand scrubs and as a skin disinfectant due to its broad-spectrum antimicrobial activity. It adheres to the skin and has lasting effects, making it a preferred choice in many clinical settings.

Each of these substances serves the purpose of reducing microbial load and preventing infection, thus highlighting that all the options are valid examples of antiseptics.
