The purpose of cylinders used in refrigeration is to store and transport refrigerants under pressure. Refrigerants are substances that absorb and release heat as they circulate in a refrigeration system, and they must be kept in a controlled environment when stored.

These cylinders are specifically designed to withstand high pressure and safeguard the integrity of the refrigerants, preventing leaks and ensuring safe handling. When transporting refrigerants, it is crucial to maintain their state and pressure for effective use in refrigeration systems. High-pressure cylinders allow for the safe containment of gases in a compact form, which is essential for the convenience and performance of refrigeration applications.

While other options mention the storage and transport of fuels or aspects like filtering refrigerants and measuring temperatures, they do not pertain to the primary function of cylinders in the context of refrigeration. The focus of cylinders is strictly on containing refrigerants, making option B the most accurate answer regarding their purpose.
