Option : (B) (i)-(c),(ii)-(a),(iii)-(d),(v)-(b)

Schottky and frenkel defects are types of a S toichiometric defect. crystalline solids have Long range order in arrangement of constituent particles. Face-Centred Cubic (FCC) has ABC ABC ..... like pattern of Layers. F-centres formed in which metal excess defect,due to anionic vacanies.
