Which term is used to describe the source that harbors a disease agent according to the provided material?

• A. Host
• B. Reservoirs
• C. Subjective
• D. Verbal communication

Answer: (B)

The main idea is understanding what serves as the source that harbors a disease agent. A reservoir is the natural habitat where the pathogen lives, survives, and multiplies, keeping the agent present in the environment or population. This can be a living organism like an animal or person, or an inanimate environment such as water or soil. Knowing the reservoir helps explain how an infection can persist and potentially be transmitted to others. A host is the organism that actually bears the pathogen and may become sick, but the term asked for here specifically describes the source where the agent lives and remains, which is why reservoirs is the best fit. The other options don’t describe that source role.
