Final answer:

First-class levers, such as seesaws and wheelbarrows, have the fulcrum positioned between the effort force and the load.


Step-by-step explanation:

First-class levers are a type of simple machine that have the fulcrum positioned between the effort force and the load. Examples of first-class levers include seesaws and wheelbarrows. In a seesaw, the fulcrum is in the middle, with the effort force applied on one side and the load on the other side. Similarly, in a wheelbarrow, the wheel acts as the fulcrum, the effort force is applied by pushing down on the handles, and the load is the weight being carried in the wheelbarrow. Therefore, the correct answer is P) two of the above.
