A certain lever has a mechanical advantage of 3. What class(es) of lever could it be?

A. Third-class only
B. First-class or third-class
C. Second-class or third-class
D. First-class or second-class

The mechanical advantage of a 3rd class lever is always less than 1. For this class of levers, the input effort is higher than the output load, which is different from second-class levers and some first-class levers. However, the distance moved by the load is greater than the distance moved by the effort.
