The correct answer is: **A. The fulcrum is between the load and effort.**
In first class levers, the fulcrum is located between the load (the object being moved) and the effort (the force applied), whereas in second class levers the load is between the fulcrum and the effort, and in third class levers, the effort is applied between the fulcrum and the load.
