Statement I: is more likely to show Schottky defect while LiI is more likely to show Frenkel defect. — Solid State Chemistry Question

Question

Statement I: $KCl$ is more likely to show Schottky defect while LiI is more likely to show Frenkel defect. Statement II: Schottky defect is more likely in ionic solids in which cations and anions are of comparable size while Frenkel defect is more likely in ionic solids in which cations and anions have large differences in their ionic sizes.
