I think in sandy road we did not fall I think due to more friction between sand and feet it is difficult to walk because sand has more contact forces upon feet so it is difficult to walk.

Option c is correct.

If friction is more then it is difficult to walk so option c is correct.

If friction is not it all then we can't walk. And if there were more friction then also we can't walk.
Friction is not the point here, here the piont is lithology of sand. Car d'nt move easily in sand due to same problem.

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 more frictional force between your feet and the path.
So it is difficult to walk if there is more frictional force and also less frictional force.
When your feet stick, that means there is more frictional force between your feet and the path.
So it is difficult to walk if there is more frictional force and also less frictional force.

Friction is responsible to hold the object in its place firmly. As there is more friction between concrete and feet it is more easy to walk on concrete than on muddy road. Hope its clear.

Friction is required for walking, and friction between foot and sand is less than that of walking on concrete road so that it is easy to wake on concrete road than on sand.

It is all about of friction. There is less friction between sand and feet by that the more time is needed to walk on sand so by that the magnitude of force get decrease so it difficult to walk on sand.

Since concrete road is more leveled than that of sand, the contact area is more with the feet so that friction will be more. So can walk easily on concrete.
