Class II cavities involve the proximal surfaces of premolars and molars, making statement a) correct. Restoring class II cavities may indeed require the use of dental amalgam or composite resin, making statement b) correct. The restoration for class II cavities should provide both mechanical and esthetic considerations, making statement c) correct. The only statement that is not correct is d) Class II cavities are typically found on the incisal edges of anterior teeth.
