Answer

Brief Explanations:

Engine oil acts as a lubricant. It creates a thin film between moving parts, reducing direct contact and thus friction by making the parts slippery. Cooling the engine is a different function of coolant, and making parts sticky would increase rather than reduce friction.

Answer:

C. making the parts slippery
