Correct Answer - C
The addition of extra electron is difficult to the atom having stable configuration and so electron gain enthalpy will be positive. Similarly the removal of electron is quite difficult from stable configuration and so ionisation enthalpy is higher. However `EN` remains unaffected because it neither involves gain nor loss of electron .
