The mechanical advantage (MA) of a lever can be calculated using the formula:

\[ \text{Mechanical Advantage} (MA) = \frac{\text{Effort Arm Length}}{\text{Load Arm Length}} \]

In this case, the effort arm length is 15 meters and the load arm length is 5 meters. Plugging in the values:

\[ MA = \frac{15 , \text{meters}}{5 , \text{meters}} = 3 \]

Therefore, the mechanical advantage is 3.

So, the correct response is 3.
