Toxicity is best defined as which of the following?

• A. Something that is poisonous to the body
• B. A process of rehabilitation
• C. A confidentiality term
• D. A training evaluation

Answer: (A)

Toxicity is the property of being poisonous to the body. It describes how harmful a substance can be when it interacts with living tissue, and it depends on factors like how much of the substance is present, how long exposure lasts, and how the body processes it. The idea is specifically about harm and poison, not about processes of rehabilitation, privacy terms, or evaluating training. Rehabilitation refers to restoring function after injury, a confidentiality term covers privacy and protection of information, and a training evaluation is about judging how well a training program works.
