In rear wheel drive cars and trucks, the engine turns:

The correct response highlights the role of the driveshaft in rear wheel drive vehicles, which is critical for transmitting power from the engine to the rear wheels. In rear wheel drive cars and trucks, the engine generates power that is sent to the transmission. From the transmission, this power is transmitted through the driveshaft, which connects to a drive axle located at the rear of the vehicle.

The driveshaft is essential in converting the engine’s rotational energy into movement by relaying this energy to the rear axle, where it then turns the rear wheels. This configuration is fundamental in rear wheel drive systems, as it allows for improved weight distribution and handling characteristics, especially under acceleration.

The other options contain elements that either pertain to incorrect mechanical configurations for rear wheel drive systems or describe components not involved in the direct power transmission. Understanding the mechanics of how power is transmitted to the wheels helps clarify the operational principles of rear wheel drive vehicles in contrast to front wheel drive or all-wheel drive setups.
