Answer:

The correct option is;

Easier

Step-by-step explanation:

The force required to lift a given load reduces when the number of pulleys in a pulley system is increased because the number of ropes sharing the applies pulling force is increased, however, the distance by which the rope is to be pulled is doubled when the required force to lift a given load is half the weight of the load.
