Answer 2

In our everyday life, we use pulley as in an Elevator.

The correct option is b.

Elevators function like a pulley. A pulley is a simple machine which utilizes grooved wheels and a rope to lift, drop or move a load. A very powerful metal rope is attached to the top of the elevator car and moves up by a pulley wheel in the engine room over the elevator. On the opposite side of the rope is the weight which is about as heavy as the elevator car when it is half full. This balances the car.
