How can you counteract centrifugal force?

You answered correctly. Centrifugal force pushes a vehicle outward in a curve. You can counteract this by leaning into the curve, which helps balance the forces, and by reducing speed, as lower speed decreases the effect of centrifugal force. Accelerating rapidly would actually increase the force and make it harder to stay on the curve, so only answers about leaning and reducing speed are correct. Understanding this helps you maintain control when driving through bends or curves.
