Answer:
A.
Explanation:
One way to reduce friction between two objects is to apply a layer of lubrication to the surfaces that touch. Lubricants are substances that reduce friction between surfaces by smoothing over the bumps and pits in the surface, allowing the objects to slide across each other with less resistance.
