The correct choice highlights the importance of using appropriate fittings when making changes in the direction of gas piping. Fittings, factory bends, or field bends are specifically designed to alter the direction of the piping while maintaining safety and efficiency in gas flow.

Fittings are integral components that provide a secure and seamless transition in direction, which helps prevent leaks that might occur if improper methods were used. Factory bends and field bends are engineered to meet certain specifications and ensure a smooth gas flow, which is essential in maintaining the system's integrity.

Using only elbows or other components would not ensure the same level of safety or performance. Adapters are used to join two different types of pipes or connect different systems, which does not directly relate to changing the direction of gas piping. Restrictions might imply a hindrance in flow, which is not desirable when designing a gas piping system. Therefore, choosing the correct method to change the direction of gas pipe is crucial for the overall safety and functionality of a propane system.
