Quizplus · Accepted Answer

Class II restorations in Black's classification system are those that involve the proximal surfaces of premolars and molars, which may also include the occlusal surfaces. Since the restoration described involves both the occlusal and mesial surfaces of a tooth (presumably a premolar or molar given the numbering), it fits the criteria for a Class II restoration.
