Answer 1

Answer: (B)

Class II

Second-class lever - A lever in which the load lies between the fulcrum and the effort. A wheelbarrow is an example of a second-class lever. A see-saw, a long narrow board equally balanced in the middle on a fulcrum is also an example of a second-class lever.
Since in this figure the load lies between the fulcrum and the effort, so it is also a second class lever.
