What type of wiring is often used for connecting different sections of a house?

The multi-wire branch circuit is the correct type of wiring used for connecting different sections of a house. This type of circuit enables the supply of power to multiple outlets or devices from a single set of wires, usually using both hot wires and a neutral wire from different phases of a service panel. By utilizing two hot wires, the circuit can effectively share the load between the two, allowing for a higher amperage without needing additional circuits, which is efficient in terms of both material and energy usage.

Using multi-wire circuits is common in residential wiring, as it can help reduce the amount of wiring needed and can be easily configured to supply power to various areas of a home. This setup is beneficial for evenly distributing electricity and minimizing voltage drops over longer distances throughout the house.

The other options do not serve the same purpose or provide the same advantages. Single-wire circuits, for instance, typically serve only one electrical device, limiting their flexibility for connecting multiple areas. Direct circuits are not typically used in residential setups, as they usually refer to configurations not suited for general household wiring. Resistive circuits relate more to the type of load connected to a circuit (specifically, those that consume power in the form of heat) rather than the circuit configuration itself for supplying power throughout
