If acceleration due to gravity was constant- constant force W was to be applied- However- due to the decrease in g we need to apply less force as we go higher- Hence the work done is lesser-

A body has weight (W) on the ground. The work which must be done to lift it to a height equal to the radius of the earth, R, is
greater than W $\times$ R
Cannot be determined
less than W $\times$ R
equal to W $\times$ R

If acceleration due to gravity was constant, constant force W was to be applied.
However, due to the decrease in g we need to apply less force as we go higher.
Hence the work done is lesser.
