Mass of an object leads to excerting force against the surface while sliding. While rolling an object then the mass gets acceleration and gets momentum with kinetic energy that reduces friction against the surface.

How can we reduce friction from sliding to rolling?
But on rolling a frictional force will be acting on the body thereby, resisting its motion. Whereas sliding can take place if there is a less frictional floor.

There are 4 types of friction
sliding
rolling
limiting-it is self adjusting friction
kinetic
lesser the surface of contact lesser the friction
the coefficient of friction is lesser in rolling fricting

lesser the surface of contact lesser the friction

In sliding more surface area is used means more friction and more loss to the object means damaged.
But in sliding less surface area or move along only one axis therefore less friction.

Frictional force in sliding > frictional force in rolling.
Because surface area of sliding will more than the rolling.
So, friction can be reduced by changing from sliding to solid.

Sliding: To move over a surface while maintaining smooth continuous contact.
Rolling: To move forward along a surface by revolving on an axis or by repeatedly turning over.

Just take an example of pulling a bucket of water from a well. It requires considerably less effort to draw the water from the well using a pulley which acts as a roller.

Coefficient of friction for rolling is a far less than that of sliding. And static state doesn't mean no force is applied on body. Friction is there to resist force.

In sliding friction whole part of the body is contact with the surface whereas in rolling friction only one part of object is in contact when the body is in motion.

Answer is wrong:
D would be correct. Friction can be brought to zero if we change the object from dynamic to static position. D would be more appropriate than A.
