Solution
The correct option is C Non contact force
We see that friction is caused by the interlocking of irregularities in the two surfaces. It is obvious that the force of friction will increase if the two surfaces are pressed hard against each other.
You can experience it by dragging a mat when nobody is sitting on it, and when a person is sitting on it. Thus, both the statements are correct.
