What boiling point defines a cryogenic fluid?

A cryogenic fluid is defined as a substance that exists at extremely low temperatures, typically used in various applications such as cooling, liquefaction of gases, and even in medical technology. The correct boiling point that defines a cryogenic fluid is below -150 degrees Fahrenheit. At this temperature or lower, fluids can exhibit behaviors and characteristics that are significant in cryogenics, such as drastically reducing molecular activity, which allows for unique applications in science and industry.

This definition generally aligns with standard practices in the field, establishing the threshold for what qualifies as cryogenic. While other options represent lower temperatures, they do not accurately reflect the established definition for cryogenic fluids, which specifically identifies -150 degrees Fahrenheit as the threshold for this category.
