Solution (By Examveda Team)

The correct answer is option C. Better weight distribution.

In commercial vehicle layouts, the positioning of the engine forward, rear, or under the floor is mainly done to achieve better weight distribution. Weight distribution plays a crucial role in the overall performance and stability of a commercial vehicle.

When the engine is located forward, it helps distribute the weight more evenly between the front and rear axles. This improves the balance of the vehicle and enhances its handling and stability, especially during cornering and braking.

Alternatively, in some commercial vehicles, the engine may be located at the rear or under the floor. This configuration also helps in achieving better weight distribution by placing a significant portion of the vehicle's weight over the rear or central axles. This can provide better traction, especially in vehicles designed for off-road or heavy-duty applications.

The other options mentioned in the question, such as better utilization of space, increase fuel economy, and reduce the weight of the chassis, are also important considerations in commercial vehicle design but may not be the primary reasons for determining the engine location. Hence, the correct answer is option C. Better weight distribution.
