Answer:
The correct option is the last option.
Explanation:
Generally, when trying to create a mechanical advantage of a lever for an apparatus or a machine, <u>the load is usually moved closer to the fulcrum</u>. Hence, if a lever has a total length of 12 meters and the fulcrum is placed at 6 meters (the center), the best way (based on the previous statement) to double the mechanical advantage of the lever is <u>to move the fulcrum 4 meters toward the side on which the force is applied</u>. The correct option is the last option.
