Answer: Option B.
A see saw, chin raise.
Explanation:
A lever is a machine that can rotate and consist of a beam which is pivoted to fulcrum.
There are three classes of lever, the first class lever, second class lever and third class lever. These three classes of lever are classified base on the positions of effort, fulcrum and Load.
In first class lever, fulcrum comes between the effort and load. Examples is scissors , see saw, pliers. This is because effort is applied on the one side of the fulcrum and load is on the other side. Therefore, the childhood demonstration of first class lever motion is see saw and chin raise.
In the second class lever, load come between effort and fulcrum e.g wheelbarrow, bottle opener.
In the third class lever, effort comes between fulcrum and load e.g hammer, broom.
