(d) Chlorine has highest tendency to gain an electron and its electron gain enthalpy (-ve) is high. Explaination for other options. O and S belong to group 16 but S has larger tendency to accept electron. And Na dont gain electron. It is e doner doe to metallic property.

The answer is Cl(g), because of the property of electron gain enthalpy, and it depends on electronegativity and the size of the atom if u will see here the most electronegativity atom is Oxygen(O), but the size of oxygen is smaller than the chlorine, so the electron density will be more on Oxygen, both...

The answer is Cl(g), because of the property of electron gain enthalpy, and it depends on electronegativity and the size of the atom if u will see here the most electronegativity atom is Oxygen(O), but the size of oxygen is smaller than the chlorine, so the electron density will be more on Oxygen, both the property makes favor to the chlorine atom, even if u will see in the hole periodic table Chlorine has the highest electron gain enthalpy.
