This illustration shows an example of a lever, which is a simple machine that helps lift or move objects by applying force to one end and fulcrum at the other. Option B, an inclined plane, is incorrect because it is a flat surface that is used to move objects up or down a slope, while the illustration depicts a curved object. Option C, a pulley system, is incorrect because it typically involves a rope or chain and is used to lift heavy objects, while the illustration shows a solid object being lifted. Option D, a wheel and axle, is incorrect because it is a type of lever, specifically a modified version where the fulcrum is at the center and the effort is applied at the rim, whereas the illustration shows a typical lever with the effort applied at one end.
