Explanation:

Step1: Recall lever - principle formula

The formula for the effort - force ($F_e$) and load - force ($F_l$) in a lever is $F_e\times d_e=F_l\times d_l$, where $d_e$ is the effort arm length and $d_l$ is the load arm length. For a given load ($F_l$), the effort force $F_e=\frac{F_l\times d_l}{d_e}$. To minimize $F_e$, we need to maximize $d_e$ and minimize $d_l$.

Step2: Analyze the levers

In a first - class lever, the fulcrum is between the effort and the load. By observing the levers, we can see that the lever with the longest effort arm and the shortest load arm will require the least amount of force. Assuming the load (the box) is the same for all levers, we look at the ratio of the load arm to the effort arm. Lever C has the longest effort arm compared to the load arm among the given first - class levers.

Answer:

G. Lever C
