The correct response is Class 1 and 2.

In a Class 1 lever (like a seesaw), the effort and load are on opposite sides of the fulcrum, and it can be configured to increase force depending on the placement of the fulcrum. In a Class 2 lever (like a wheelbarrow), the load is in the middle, allowing a smaller effort to lift a larger load.

Class 3 levers, on the other hand, always require a greater effort to move the load, and therefore do not increase force.
