An inhibitor is described as:

• A. a substance that slows down or stops a reaction
• B. a substance which inhibits the properties of a catalyst
• C. a substance formed during the reaction and does not participate in the reaction
• D. a substance which prevents formation of products in a reaction being most reactive

The correct option is A a substance that slows down or stops a reaction

A reaction inhibitor is a substance that decreases the rate of, or prevents, a chemical reaction. A catalyst, in contrast, is a substance that increases the rate of a chemical reaction.
