Blood borne pathogens are disease-causing organisms transferred through contact with blood or other body fluids.

• A. Blood borne pathogens
• B. Bacteria
• C. Viruses
• D. Carriers

Answer: (A)

Bloodborne pathogens refer to disease-causing organisms that can be transmitted through contact with blood or other body fluids. The statement matches that idea exactly, because it names the category itself rather than a specific type of organism. Bacteria and viruses are examples of pathogens, but they aren’t defined by the route of transmission; the term bloodborne pathogens focuses on those organisms that can spread via blood or contaminated fluids. Carriers are people who may harbor these pathogens, not the organisms themselves. So the best choice is the term that names the category defined by transmission through blood and body fluids.
