Solution

Hello Sri Charan,
You perhaps are acquainted with the formula for frictional force.

F=kNwhere k is the coefficient of friction and N is the normal force from the surface. Both of these do not depend on the area of contact.
So Opt D is the answer
Whereas K depends on nature of surface and its type
