Which of the following best describes "toxic" materials?

The term "toxic" refers to materials that can cause serious injury or harm to living organisms, including humans, animals, and plants. This definition encompasses a wide range of harmful effects, which can vary depending on the dosage, exposure duration, and the specific characteristic of the material itself. Toxic materials can disrupt bodily functions, lead to various health issues, and even cause death in severe cases.

This understanding aligns with the classification of toxic substances as those that pose a significant risk to health and safety, distinguishing them from materials that may be considered non-toxic or beneficial. While the other options touch on aspects of materials' effects, they do not accurately capture the comprehensive and potentially severe nature of toxicity. For example, materials with low health risks, beneficial uses in agriculture, or those only harmful to humans do not encompass the full scope of what qualifies as toxic.
