Solution

The correct option is B
Force multiplier

In a bottle opener, the effort arm (distance from effort point to the fulcrum) is bigger than the load arm (distance from load point to the fulcrum).
The lever which has an effort arm greater than the load arm is known as a force multiplier. Hence, a bottle opener acts as a force multiplier.
