Question

Schottky defects occurs mainly in electrovalent compounds where (A) positive ions and negative ions are of different size (B) positive ions and negative ions are of same size (C) positive ions are small and negative ions are big (D) positive ions are big and negative ions are small

When equal number of cations or anions are missing from their lattice sites (to maintain electrical neutrality), then the defect is called Schottky defect. The defect is observe in highly ionic compounds which have cations and anions of similar size eg NaCl, KCl etc
