Which electrical issue poses a risk for creating potential fire hazards?

Overloaded circuits pose a significant risk for creating potential fire hazards because they can cause overheating of wires and components. When too many devices are connected to a single circuit, it can exceed the circuit's designed amperage. This excess current flow generates heat, which can damage insulation and, in severe cases, lead to arcing or sparks that ignite flammable materials nearby. Ensuring circuits are not overloaded is crucial for maintaining electrical safety in a home.

In contrast, properly grounded outlets, flexible wiring near appliances, and carbon monoxide detectors are not safety issues leading to fire hazards. Proper grounding helps prevent electrical shock and ensures that fault currents safely discharge into the ground. Flexible wiring, if appropriately installed and maintained, is designed for safe use around appliances. Meanwhile, carbon monoxide detectors are essential for detecting gas leaks and preventing poisoning but do not directly relate to fire hazards in the way overloaded circuits do.
