Single pulley does not provide any mechanical advantage, it only changes the direction of force while an inclined plane provides mechanical advantage. This means the efforts required to life the same amount of load on an inclined plane is lesser than that by a single pulley. (Pulley provides mechanical advantage only if we use more than one pulley).Lesser the inclination more is mechanical advantage and lesser the effort. That means the correct answer should be 'D'
