A third-class lever is characterized by having the force applied between the fulcrum and the load. In this case, tweezers serve as an excellent example because when you squeeze the handles (applying the force) at one end, the tips (where the load is applied) are effective for picking up or holding objects, with the fulcrum located at the joint of the tweezers.

This configuration allows for a greater range of motion at the tips of the tweezers compared to the force applied at the handles, which is a defining feature of third-class levers. The other options do not meet this criterion as clearly as tweezers. For instance, a bottle opener operates as a first-class lever, a wheelbarrow exemplifies a second-class lever, and a seesaw acts as a first-class lever as well, where the fulcrum is in the middle with the load and effort on opposite sides.
