4*4 means, 4 wheel and 2nd 4 means all are driving wheel.

What is meant by 4 * 4 vehicle? @Mathesh.

I think option C is correct as the rigid suspension will also increase the tyre-to-ground contact characteristic.

Rigid axle suspension systems are designed for the rear of larger vehicles, such as the Dodge RAM. These systems have a solid beam that extends between two wheels. If you hit a bump on the road, both tires will receive the same impact. This means you aren't going to get the same smooth ride that you would in a vehicle with an independent system. They can, however, carry heavier loads and are great for off-roading and towing, which is why they are commonly found in the larger 4x4 vehicles.

I didn't get, please explain.
