A block hangs freely from the end of a spring. A boy then slowly pushes the block upwards so that the spring becomes strain free. The gain in gravitational potential energy of the block during this process is equal to:

Work done by the boy against the gravitational force acting on the block

Loss of energy stored in the spring minus the work done by the tension in the spring

Work done on the block by the boy plus the loss of energy stored in the spring

Work done on the block by the boy minus the work done by the tension in the spring
