I think option C is right since friction stands for the opposition offer in a walk.

Option C is correct.

The answer is c.

Option C is right.

When we drag a drum, it has more friction on the surface, while when we roll a drum it has less friction. Hence rolling a drum causes less friction and easy to transport.

Similarly walking on sand causes more resistance ( i.e 1 more friction) on foot, causing difficult to walk. While on concrete there is lesser resistance (i.e 5 less friction compared to that of sand and foot), resulting in an easier way to walk.

In addition as explained earlier by Prashant - When your feet slip, that means there is less frictional force between your feet and the path you walk.

When your feet stick, that means there is a more frictional force between your feet and the path.

So it is difficult to walk if there is a more frictional force and also less frictional force.

Hence I seems option C is correct.

Option C is correct.

Because if there is more friction then it is more difficult to walk than in concrete.

The reaction of a hard floor on the feet is much more than that applied by the sand on the feet. A part of the action by the feet on the sand is dissipated within the sand particles due to the lower friction within the particles as compared to the layers of hard surface.

I think option B is correct because when friction is less than one will feel quite hard to walk like in a slippery way the friction will be less between our feet and path which may make us fall down.

So option B is correct guys.

Answer Should be "C".

Because Friction is more in the case of the sandy road than the concrete road.

Yeah, option B is right because friction helps us to walk and where there is a less friction like on the sand, it is difficult to walk and therefore on the rough surfaces line get road there is more friction which helps us to walk easily.
