Solution
The correct option is A Fulcrum A pulley is a simple machine consisting of a wheel and an axle through which a rope passes. The load is attached at one end of the rope and the other end of the rope is the effort point which we can pull in the downward direction to lift the load on the other end. A fulcrum is a fixed point in a lever about which it moves. Hence it is not a part of a pulley.
