The correct answer is: Yellow

The symbol for a type D extinguisher is yellow. This color coding is specifically designated for extinguishers used for combustible metals such as magnesium, sodium, and potassium, which require a specialized type of extinguishing agent to combat fires effectively. In the fire safety context, color coding serves as a quick reference to guide individuals in selecting the appropriate extinguisher based on the type of material that is burning. Yellow indicates that it is meant for metal fires, ensuring that users do not mistakenly use a standard extinguisher, which may not be effective and could potentially cause the fire to worsen. This specific labeling aids in promoting safety and efficiency during emergency situations by helping users identify the correct type of extinguisher rapidly.
