If the Assertion is correct but Reason is incorrect.

(C) The Assertion is correct because elements tend to lose electrons to achieve a stable noble gas configuration.The Reason is incorrect because ionization enthalpy is defined as the energy $required$ (absorbed) to remove an electron from an isolated gaseous atom,not the energy $released$.
