What is the basic difference between the terms electron gain enthalpy and electronegativity?

Options:
A Electron gain enthalpy measures the energy change when an atom gains an electron to form an anion, while electronegativity measures an element's ability to attract electrons in a chemical bond.
B Electron gain enthalpy and electronegativity are two different names for the same property.
C Electron gain enthalpy measures the ability of an element to attract electrons, while electronegativity measures the energy change when an atom loses an electron.
D Electron gain enthalpy and electronegativity both measure the energy change when an atom gains an electron but in different units.

The correct answer is:
Electron gain enthalpy measures the energy change when an atom gains an electron to form an anion, while electronegativity measures an element's ability to attract electrons in a chemical bond.

Solution:
Correct Option is : (A)
Electron gain enthalpy measures the energy change when an atom gains an electron to form an anion, while electronegativity measures an element's ability to attract electrons in a chemical bond.
