Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Frenkel defect is the defect which is created when a cation leaves its appropriate site in the lattice and occupies an interstitial site. The closeness of the charge brought about by Frenkel defect tends to increase the dielectric constant of the crystal.
