Which term refers to a cleansing agent?

• A. Device
• B. Flood
• C. Detergent
• D. Absorb

Answer: (C)

A cleansing agent is a substance used to remove dirt from surfaces by helping water to wash it away. Detergent fits this idea because it’s specifically formulated to clean: it contains surfactants that lower water’s surface tension and emulsify oils, so dirt can be lifted up and suspended in the rinse water for easy removal. The other terms don’t describe a cleaning product: a device is a tool or machine, a flood is a large overflow of water, and to absorb is the action of taking in a liquid rather than a product used to clean. Detergent is the term that refers to a cleansing agent.
