The correct choice is three-wire cable with ground because this type of cable is specifically designed for wiring setups that include three-way switches. Three-way switches allow you to control a single light or a set of lights from two different locations. To achieve this, the circuit needs both a common wire and two travelers.

The three-wire cable typically includes one black wire, one red wire, and one white wire, along with a ground wire. The black and red wires serve as the traveler wires that connect the two switches, allowing for the toggling of power to the light from either switch. The white wire is used as a neutral, while the ground wire enhances safety by providing a path for any fault current.

Using a different type of cable, such as two-wire or multi-conductor cables, would not provide the necessary connections for two switches to communicate effectively, nor would it include the safety features that the grounding wire provides. Hence, for a proper and safe installation of a three-way switch system, three-wire cable with ground is required.
