Correct Answer:
B. Class 1
Explanation:
In a Class 1 lever, the fulcrum is positioned between the effort and the load. This arrangement allows the lever to change the direction of the input force, meaning that pushing down on one end results in the load moving upward on the other. Common examples of this configuration include a seesaw, a pair of scissors, or a crowbar, where the pivot point remains centered between the applied force and the object being moved.
