Options
- A(a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
- B(a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)
- C(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
- D(a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)
Correct answer

Step-by-step solution
(a) Frenkel Defect-formed in ionic compounds where an ion is missing from its lattice site and occupies interstitial site. Compounds suffering from such defects does not have any change in their density. (b) Schottky defect-Observed inionic compounds where equal number of ions are found missing from their lattice site. Such compounds have lower density. (c) Vacancy defect-Observed in non-ionic solids where either an anion or cation is missing from their sites. Density of such solids are lower. (d) Interstitial defe
