Solution

The correct option is D All the statements are incorrect
Friction opposes relative motion between two surfaces in contact. Rough surfaces develop friction because of interlocking of irregularities. However, interlocking of irregularities is not the sole cause of friction. Smooth surfaces can also develop friction because of formation of bonds between them. This is referred to as "adhesion".
