Which term describes the disease-causing agent in general?

• A. Bacteria
• B. Pathogen
• C. Virus
• D. Fungus

Answer: (B)

The main idea is the broad label for anything that can cause disease. A pathogen is the general term for any organism or agent that can cause disease in a host, including bacteria, viruses, fungi, parasites, and even some non-living agents like prions. Because it covers all possible disease-causing agents, it’s the best answer when the question asks for the general term. The other options are specific types of disease-causing agents. Bacteria, virus, and fungus each describe a particular category, not the overall concept. They’re all examples of pathogens, but they don’t convey the wide, inclusive idea that the term pathogen does.
