Solution

The correct option is A adhesion
When two smooth surfaces are in contact, bonds are formed between them because of which they become sticky. This is referred to as "adhesion" and is responsible for friction between two smooth surfaces. To slide the surfaces over each other, these bonds need to be broken.
