Solution
The correct option is C Interlocking decreases
Friction is caused due to interlocking of irregularities present on the surfaces in contact. When a lubricant is applied, it forms a layer between the two surfaces. This helps in reducing interlocking and hence friction. However, friction can not be totally eliminated.
