A disorder of structure or function in a human, animal, or plant with a known cause and a distinctive group of symptoms is called what?

• A. Disinfection
• B. Dysphagia
• C. Disease
• D. Disease process

Answer: (C)

A disease is a disorder of structure or function with a known cause and a distinctive group of signs and symptoms. This combination—a specific etiology and a recognizable clinical presentation—is what makes this term the best fit for the description. Disinfection is the process of removing or killing pathogens, not a condition. Dysphagia is a symptom, specifically difficulty swallowing, rather than a full disorder with a defined cause and characteristic symptom set. A disease process describes how a disease develops over time, not the condition itself. So the term that matches the description is disease.
