The typical range of voltage for residential wiring in the United States is accurately described by the choice that states 120/240 volts. This is due to the standard voltages provided by the electrical systems in American homes, which utilize a split-phase system.

In residential applications, 120 volts is commonly used for standard outlets, lighting, and appliances, which provide sufficient power for everyday usage. The 240 volts is typically employed for larger appliances such as dryers, ovens, and HVAC systems that require more power to operate efficiently.

Understanding this voltage range is essential for anyone working in electrical installations and maintenance, as it ensures the right voltage supply for different devices, promotes safety, and adheres to building and electrical codes. The other ranges provided do not reflect typical residential standards or would be more applicable to different types of circuits or industrial settings.
