The answer is D. With mechanical advantage, less work is put in for a better result. It can apply force in a shorter distance, but increase distance itself.
Mechanical advantage allows you to apply a force over a short distance to increase the distance an object moves.
Explanation;
Mechanical Advantage of a machine is a measure of the ratio of output force to input force in a system. It tells you how many times the machine multiplies force. A machine can increase force and distance but not at the same time.
In the force-distance trade-off if the force increases then the distance would decrease. They can not both increase at the same time.
