Answer: (C)

In fuel gas systems, yellow is the standard color marking used for fittings. This color is specifically designated for gas-related systems to ensure safety and identify components associated with fuel gases easily. The use of yellow helps workers and emergency responders quickly recognize gas fittings and the associated risks. This aids in preventing accidents and ensuring proper handling of fuel gas systems. Different colors are used in various industries to signify different substances or services. For instance, red typically indicates fire-related equipment; green is commonly associated with water; while blue is often used for potable water. The unique use of yellow for gas fittings provides a clear visual cue that distinguishes them from other types of plumbing and service fittings, thereby promoting safety in environments where multiple systems may be in close proximity.
