Detailed Solution

Friction is the force that opposes the relative motion between two surfaces of objects when they come in contact. The frictional force is the force that resists sliding or rolling one solid object over the other. The frictional force will always slow down a moving body.
Using lubricants, such as oil or grease, reduces friction between surfaces by creating a slippery layer. In contrast, the other options—increasing roughness, increasing surface area, and polishing surfaces—all contribute to enhancing friction between objects in contact.
