Explanation:
Detailed explanation-1: -1 Answer. Due to missing of ions, the overall density of the crystal decreases in the schottky defect.
Detailed explanation-2: -<br> (D) A larger anion is in interstitial position. No such crystal exists in which larger anion is in interest site-thus incorrect.
