Given answer is correct as the specific volume of gas is directly proportional to its temp and at low temp it's value will be lesser. Now in case of open system work input is directly proportional to specific volume so at low temp work input will be lesser.
answer should be D...work done of compressor = enthalpy at exit - enthalpy at inlet...max temperature of inlet will yield a lower work done...
