Hazard is a potential source of danger.

• A. Conductor
• B. Insulator
• C. Load
• D. Hazard

Answer: (D)

Hazard refers to a condition or situation with the potential to cause harm. In electrical safety, a hazard is anything that could lead to injury, electric shock, fire, or equipment damage. The statement matches this idea exactly: the hazard is the potential source of danger, not a specific object itself. Conductor, insulator, and load are concrete electrical components—conductors carry current, insulators resist it, and loads use energy. While any of these can create a hazard if conditions are unsafe (like exposed conductors or damaged insulation), they describe equipment, not the risk itself. Therefore, hazard is the correct concept because it identifies the possibility of danger rather than describing a physical part of the circuit.
