Hint: The frictional force is the force applied by the surface on the object to move across it. Static friction is the frictional force that exists between the stationary object and the surface on which the object is resting.

We know that the coefficient of static friction is also equal to the tangent of the angle of the friction.
The magnitude of the limiting (maximum) static frictional force depends upon the nature of the surfaces in contact and on their roughness. It is independent of the size or area of the surfaces.

$\therefore$ The coefficient of static friction between two surfaces depends on the nature of surfaces. Hence, option (A) is the correct option.

The coefficient of static friction is represented by ${\mu}_s$.
