Answer
It is easier to lift a heavy stone under water than in air because due to the effect of upthrust, the stone experiences an upward buoyant force that balances the true weight of the stone which is acting in the opposite direction.
Hence, the weight of the stone immersed in water appears less than the actual weight.
