**Hint**Classes of lever are only based on the configuration or arrangement of the fulcrum, effort and load, not their exact location.The fulcrum is the pivot point, the effort is where force is applied by external agents and the load is the force the effort aims to move.

**Complete step by step answer**

A lever is a simple machine which consists of a beam pivoted at a point, commonly called fulcrum. As every machine, levers are built to increase efficiency in doing work. In general, different levers are configured in different ways. It is understood that there are three different classes of lever dependent on the arrangement of their load point, effort point and fulcrum. In any lever, the effort is called input force while the load is called output force. A famous example is a seesaw.

First class lever or commonly class 1 lever: These types of lever have their fulcrum in between their load (or resistance) and their effort. This is to say that the load is acting on one side, of the fulcrum and the effort applied on the other side.

Second class lever or class 2 lever: This is a class of lever whereby the load is in between the fulcrum and the effort, that is to say, that the fulcrum is on one side of the load while the effort is on one side

Third class lever or class 3 lever: This is the class of lever whereby effort is between the load and fulcrum.

Comparing the above definitions with the figure in question, we can conclude that it is a Class 2 lever.

**Hence, the correct option is B.**

**Note**

In application, levers are often used to multiply or amplify force. That is to say, to use a lower force to generate a higher force. Such levers are said to be mechanically advantaged. However, even in such levers, energy is always conserved obeying the fundamental principle of conservation of energy.
