Bloodborne pathogens are transmitted through blood and through other body fluids that can be contaminated with blood. The best choice lists fluids that can carry bloodborne pathogens when there is blood present, including blood itself and other bodily fluids that might be contaminated.

So, the set that includes mucus, urine, feces, and blood best reflects the kinds of substances that could harbor bloodborne pathogens.
