C. Inclined plane
Explanation
An inclined plane is a simple machine that consists of a flat surface that is raised at one end. It is used to reduce the amount of force needed to move an object by increasing the distance over which the force is applied. By using an inclined plane, the force required to move an object is spread out over a longer distance, making it easier to overcome the force of gravity and move the object.
