Which one of the following compounds shows both, Frenkel as well as Schottky defects?
A ZnS
B AgBr
C AgI
D NaCl

Detailed Solution

AgBr is unusual in that it shows both Frenkel defects (due to the small size of $Ag^+$, which can move to interstitial sites) and Schottky defects (as the sizes of $Ag^+$ and $Br^-$ are not too different).
