Solution
The correct option is B Class II In class II levers, the fulcrum and the effort are at the two extremes ends of the lever and the load is somewhere in between the effort and the fulcrum.
The M.A. of a lever =Effort armLoad arm
Since, the effort arm is always longer than the load arm, from the equation above, it is clear that M.A. of a class II lever is always greater than 1.
