Choice C rationale:

Discarding used syringes in appropriate containers is important for safety, but it does not directly prevent the spread of pathogens.

Choice D rationale:

Properly disposing of contaminated equipment is important, but hand hygiene is more effective at preventing the spread of pathogens.
