Solution
The correct option is B Liquid Nitrogen and Liquid Helium
Liquid nitrogen is the most commonly used element in cryogenics. It is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water makes it extremely useful in a wide range of applications.
Liquid helium is also commonly used and allows for the lowest attainable temperatures to be reached.
