The term for the effect of the substances on the body or an organ is called what?

• A. Response
• B. Toxicity
• C. Hazard
• D. Efficacy

Answer: (A)

The effect a substance has on the body or an organ is its response. This captures the observable outcomes produced by exposure, whether helpful (like relief of symptoms) or harmful (like tissue irritation or organ stress). The other terms have narrower meanings: toxicity refers specifically to harmful effects, hazard is the potential for harm in a given situation, and efficacy is about achieving the desired therapeutic effect. So "response" best describes the actual effect the substance produces in the body.
