Correct Answer: Option A

1. A force that resists the relative motion of two surfaces sliding over each other is known as frictional force.
2. When a force is applied to an object to make it move, the frictional force opposes the motion of the object. Thus, the object comes to rest after covering a certain distance.
3. The more the frictional force is, the less the distance covered by the object will be.
4. The frictional force depends upon the roughness of the surface. The rougher the surface is, the more the frictional force will be, and therefore, the less the distance covered by the object will be.
5. The least rough surface from the options provided is a wet marble floor. Thus, the frictional force will be the least here.
6. So, the car will cover the most distance on the wet marble floor.

Incorrect options:

Option B

A dry marble floor also has less frictional force, but it is more than that of the wet marble floor. So, the car won't cover the most distance on it. Thus, this option is incorrect.

Option C

A newspaper has more frictional force than a marble floor. So, the car won't cover much distance on it. Thus, this option is incorrect.

Option B

A towel has the most frictional forces in the given options. So, the car will cover the least distance on it. Thus, this option is incorrect.

Hence, option A is correct.
