Vedclass · Answer

(C) The correct statement is that the trapping of an electron in the lattice leads to the formation of an $F$-centre. Frenkel defect is a dislocation defect where an ion leaves its lattice site and occupies an interstitial site. Schottky defect is a vacancy defect where equal numbers of cations and anions are missing from the lattice,which leads to a decrease in the density of the solid.
