Answer:
B) The pulley helps us change the direction of the force.
Explanation:
Pulleys help us by changing the direction of the force we use to lift an object. By using a pulley, we do not have to pull up on a rope to lift a heavy object attached to it, but instead we can pull down on it. Think of a flagpole as an example.
