Which of the following is a biological toxic agent?

Explanation:
Biological toxic agents are poisons or harmful substances produced by living organisms or present as living organisms themselves. Bacteria fit this category because they are living microorganisms that can cause disease and, in some cases, produce toxins (exotoxins or endotoxins) that harm the body's cells. Radiation is not biological—it's a form of energy that can damage tissues, a physical hazard. Lead is a chemical toxicant, a heavy metal that disrupts biological processes. Noise is a physical hazard related to sound energy and does not involve a biological toxin. So, the biological toxic agent is the bacteria.
