Answer: (1). O has the highest positive electron gain enthalpy

Explanation:

Because of the the more energy gained due to the higher internal repulsion between the electrons.

The electron gain enthalpy of an element is defined as the energy gained by the acceptance of extra electron from the neutral isolated gaseous atom to form gaseous negative ion which is an anion.
