E)None of the answers is correct;all of these can be reservoirs of infection.

Accepted Answer

All the options listed can serve as reservoirs of infection. A sick person and a sick animal can directly harbor pathogens. A healthy person, often referred to as a carrier, can harbor and spread pathogens without showing symptoms. Hospitals, due to the concentration of sick individuals and invasive procedures, can also be significant reservoirs of infection, known as nosocomial infections.
