The answer is C. Universal Precautions
The OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030) contains a lot of requirements that aim to protect you in the workplace. Employers are required to implement the use of universal precautions and these includes treating all human blood and other potentially infectious material, as if known to be infectious, for bloodborne pathogens.
