Solution

The correct option is B
Zero

The Born-Haber cycle, is based on Hess Law or Law of constant heat summation which states that the standard enthalpy of reaction is the sum of algebraic sum of the standard enthalpies of reactions into which the overall reaction may be splitted. So the change in enthalpy around a cycle is zero.
