None of the four options is correct.
A class 3 lever gives a mechanical disadvantage (MA < 1) — it does not reduce the force or the work. Its advantage is that it increases the distance and speed (range of motion) of the load for a given movement of the effort (e.g., the forearm, fishing rod, tweezers).
