Final answer:
A second class lever has the output force located between the input force and the pivot point. In the provided options, a bottle opener exhibits this trait, making it an example of a second class lever.
Step-by-step explanation:
A second class lever, in the context of physics, is one where the output force is located between the input force and the fulcrum, or pivot point. The output force is the force exerted by the lever on the load it is supposed to move. Based on this definition, the answer to your question is d. Bottle opener as it exemplifies a second class lever.
When you use a bottle opener, the rim of the bottle cap acts as the fulcrum, the input force is applied by your hand on the handle and the output force is exerted on the metal cap, which is located between the fulcrum and the location of the input force.
