Toxic materials can also be described as ____________.

• A. Harmless
• B. Poisonous
• C. Inert
• D. Non-toxic

Answer: (B)

Toxic materials are substances that can cause harm to living beings, so they are described as poisonous. The term poisonous highlights that exposure—whether by swallowing, breathing, or skin contact—can lead to injury or death. In contrast, harmless and non-toxic imply no harmful effects, and inert refers to chemical reactivity rather than toxicity. An inert substance might be nonreactive but could still pose hazards in other ways, while a non-toxic label would mean it doesn’t cause toxic effects.
