Ionization energies of atoms A and B are 400 and \[300\text{ }k\text{ }cal\text{ }mo{{l}^{-1}}\] respectively. The electron affinities of these atoms are 80.0 and \[85.0\text{ }k\text{ }cal\,mo{{l}^{-1}}\] respectively. Then which is the correct statement regarding electronegativity\[\chi \]?

A) \[{{\chi }_{A}}<{{\chi }_{B}}\]                                

B) \[{{\chi }_{A}}>{{\chi }_{B}}\]

C) \[{{\chi }_{A}}={{\chi }_{B}}\]                    

D) none of these
