Which term describes something that is communicable by contact?

• A. Infectious
• B. Contagious
• C. Communicable
• D. Transmissible

Answer: (B)

Contagious describes diseases that spread from person to person through direct contact or close proximity, which fits the idea of being communicable by contact. Infectious refers to diseases caused by pathogens but doesn’t specify how easily they spread. Communicable is a broader term for any disease that can be transmitted, not limited to contact, and transmissible means capable of transmission in general without pinning down the route. So, because the scenario focuses on spread by contact, contagious is the most precise fit.
