In lubrication, the primary function is to reduce friction between moving surfaces.

Explanation:
Lubrication works by creating a thin film between moving surfaces so they don’t rub directly against each other. This separation directly protects parts from material wear caused by sliding contact, which is why the primary function is to reduce wear on parts by friction. When there’s less direct contact, you get less wear, longer part life, and smoother operation. The other effects—less heat from friction and quieter operation—are important but are secondary benefits that come from reducing friction. Electrical resistance isn’t a primary concern of lubrication.
