• A. retarding force
• B. negative force
• C. frictional force
• D. none of the above

Answer 1

The correct option is C

1. When the surface of one body is made to slide over the surface of another body, a force is called into play that opposes the motion called force of friction or frictional force.
2. This force has a tendency to oppose the relative motion between the surfaces.
3. Hence option C is correct.
