Explanation:

Bio - hazard waste includes materials that are potentially infectious. Blood - contaminated items can carry pathogens. A used needle can be contaminated with blood and bodily fluids, and gauze contaminated with blood can also transmit infections. A used mask or gauze that fell on the ground may not necessarily be an immediate bio - hazard compared to blood - contaminated items.

Answer:

C. Gauze contaminated with blood, B. A used needle
