For normal cruise with no flap deployment, which configuration is used?

Explanation:
Flaps increase wing camber to boost lift at low speeds, but they also create more drag. In normal cruise you want the highest possible speed with the most efficient lift-to-drag ratio, so flaps are kept retracted. That means no flaps is the configuration used for cruise. The flap steps (one, two, or three) are variations used for takeoff or landing when extra lift at lower speeds is needed, not during normal cruise.
