___________ are any biological, chemical (including radiological), or physical agent that has the potential to cause illness or injury

• A. Contaminants
• B. Pathogens
• C. Hazards
• D. Toxins

Answer: (C)

Hazards refer to any factor that has the potential to cause illness or injury, spanning biological, chemical (including radiological), and physical agents. This broad term is the best fit because it covers all these categories in one concept, signaling possible harm regardless of the specific type.

Pathogens are limited to disease-causing organisms, so they don’t account for chemical, radiological, or physical risks. Toxins are harmful substances produced by organisms, which is narrower and doesn’t include other hazard sources like a broken glass or radioactive material. Contaminants describe unwanted substances that may be present, but the term focuses on presence rather than the inherent potential to cause harm across all categories.
