Vedclass · Answer

(A) Schottky defect is a type of point defect in ionic crystals where an equal number of cations and anions are missing from their lattice sites to maintain electrical neutrality.Therefore,it involves both cation and anion vacancies,not just cation vacancies.Compounds exhibiting Schottky defect typically have high coordination numbers (e.g.,$NaCl$,$KCl$,$CsCl$).Since the statement that it contains only cation vacancies is incorrect,the correct option is $A$.
