Which term describes organisms that do not require oxygen to survive?

Organisms have different oxygen needs, and this question is about those needs. The term for organisms that do not require oxygen to survive is anaerobic. Some anaerobes actually do poorly or not at all in the presence of oxygen, while others can grow without it. This contrasts with aerobic organisms, which absolutely need oxygen. The other options refer to different concepts entirely: aseptic means free from contamination or sterile technique, and bloodborne pathogens are those that can be transmitted through blood. So the best term for organisms that do not require oxygen is anaerobic.
