MediumAn element $E$ has an ionisation enthalpy value of $374 \ kJ \ mol^{-1}$. $E$ reacts with elements $A, B, C$ and $D$ with electron gain enthalpy values of $-328, -349, -325$ and $-295 \ kJ \ mol^{-1}$,respectively. The correct order of the products $EA, EB, EC$ and $ED$ in terms of ionic character is $:$
- A$EB > EA > EC > ED$
- B$ED > EC > EA > EB$
- C$EA > EB > EC > ED$
- D$ED > EC > EB > EA$
