Which caries classification describes pits and fissures of molars and premolars?

Caries are categorized by where they occur on a tooth, using a system that groups surfaces into classes. Pits and fissures on the chewing surfaces of the back teeth—the molars and premolars—fall under Class I. This category specifically covers occlusal surfaces and the pits or fissures found there, which matches the description in the question. The other descriptions refer to different locations: decay on the spaces between teeth of the back teeth is Class II, decay between the front teeth is Class III, and decay that involves the incisal edge of front teeth is Class IV. A lesion on the cervical third of facial or lingual surfaces is Class V. Therefore, pits and fissures on molars and premolars are best described as Class I.
