An antiseptic is a product applied to the skin to reduce microbes.

• A. Product applied to the skin to reduce microbes
• B. Product used to color hair
• C. Product used to remove cuticles
• D. Product used to sterilize tools

Answer: (A)

Antiseptics are products designed to be applied to living tissue, such as the skin, to reduce the number of microbes and lower the risk of infection. That exactly matches the statement describing an antiseptic: a product applied to the skin to reduce microbes.

The other options don't fit because they describe things not aimed at reducing microbes on living tissue: coloring hair is cosmetic coloring, not antimicrobial; removing cuticles is a nail service step, not related to microbial control; sterilizing tools is about killing all microbes on instruments and is used on nonliving surfaces, not applied to the skin.
