Frenkel and Schottky Defects
Frenkel and Schottky defects are types of point defects that occur in crystals. These defects are caused by the presence of missing or extra ions in the crystal lattice.
Frenkel Defect
A Frenkel defect occurs when a cation in the crystal lattice moves from its normal position to an interstitial site. This creates a cation vacancy in its original position and a certain interstitial. Frenkel defects are common in ionic crystals where the cations are much smaller than the anions.
Density of a solid remains unchanged in case of Frenkel defects because the number of ions in the crystal remains the same, only their positions change. Frenkel defects do not affect the overall charge neutrality of the crystal.
Schottky Defect
A Schottky defect occurs when a cation and an anion in the crystal lattice are both missing from their normal positions. This creates a cation vacancy and an anion vacancy. Schottky defects are common in ionic crystals where the cations and anions are roughly the same size.
Density of a solid decreases in case of Schottky defects because the number of ions in the crystal decreases. Schottky defects lead to a decrease in the overall charge neutrality of the crystal.
Conclusion
In summary, Frenkel defects occur when a cation moves to an interstitial site, leading to a cation vacancy and a certain interstitial. Density of a solid remains unchanged in case of Frenkel defects. Schottky defects occur when a cation and an anion are both missing, leading to a cation vacancy and an anion vacancy. Density of a solid decreases in case of Schottky defects.

C option is correct as the ions are present in interstitial position in crystal lattice. so density remains fixed.
D option is correct as in Schottky defect equal number of cations and anions are absent from their lattice site. so density decreases in this case
A is correct as in this defect , the ions are present in interstitial position
D option is correct as in Schottky defect equal number of cations and anions are absent from their lattice site. so density decreases in this case
A is correct as in this defect , the ions are present in interstitial position
