( A ) Compressing the gas isothermally will require more work to be done.
( B ) Which of the case (whether compression through isothermal or through adiabatic process) requires more work will depend upon the atomicity of the gas.
( C ) Compressing the gas isothermally or adiabatically will require the same amount of work
( D ) Compressing the gas through adiabatic process will require more work to be done.
