Vedclass · Answer

(B) . Frenkel defect: Shown by ionic substances with a large difference in ion sizes,e.g.,$AgCl$.$B$. Schottky defect: Shown by ionic substances with similar cation and anion sizes,e.g.,$NaCl$.$C$. Vacancy defect: Occurs when some lattice sites are vacant,leading to decreased density.$D$. Metal deficiency defect: Occurs in non-stoichiometric solids like $FeO$ (often $Fe_{0.95}O$).
