Answer:
The correct answer would be option C, Universal Precautions. 
Explanation:
Treating all human blood and other potentially infectious material, as if known to be infectious, for bloodborne pathogens is called as Universal Precautions. 
Now here it is important to know what bloodborne pathogens are. These are actually the tiny organisms, called as micro organisms, which cause illness or diseases in the human body. These are infectious microorganisms. The diseases caused by these infectious microorganisms may include Hepatitis B, Hepatitis C and HIV. This type of disease may transfer from one human to another by the exposure of blood through sharp needle like structures or injections, etc. 
So all blood must be treated before donating or transferring to other humans and this is called the Universal Precautions.
