Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Ionic solid:- Ionic Solids are solids composed of oppositely charged ions. They consist of $+$ charged cations and $-$ charged anions

Lattice enthalpy:- Lattice enthalpy is a measure of the strength of the forces between the ions in an ionic solid. The greater the lattice enthalpy, the stronger the forces. Those forces are only completely broken when the ions are present as gaseous ions
So the correct option is [A].
