(A) and $C$ are correct statements.$A$. Incorrect: Frenkel defect is favoured by a large difference in the sizes of cation and anion.$B$. Correct: Frenkel defect is a dislocation defect where an ion moves from its lattice site to an interstitial site.$C$. Correct: Trapping of an electron in an anionic vacancy leads to the formation of $F$-centers,which impart color to the crystal.$D$. Incorrect: Schottky defects decrease the density of the solid,thus affecting its physical properties.
