The discovery of a harmful ingredient led to which concept?

• A. Contaminant Hazard
• B. Toxic Substance
• C. Hazardous Compound
• D. Poisonous Ingredient

Answer: (B)

The key idea here is toxicity and toxicology: when you uncover an ingredient that can cause harm, you’re dealing with a toxic substance. “Toxic” specifically describes the potential to produce adverse effects in living systems, and it applies across different exposure routes and doses, capturing the real risk the ingredient poses. The other terms are less precise for labeling the substance itself. A contaminant is simply an unwanted substance present in a product or environment, not necessarily inherently harmful. A hazardous compound and a poisonous ingredient convey danger, but they’re less standardized in terminology; “toxic substance” is the clearer, more general label used to describe anything capable of causing harm upon exposure, regardless of whether it’s ingested, inhaled, or absorbed.
