Final answer:
The correct answer is that the five surfaces of a tooth are occlusal, mesial, distal, lingual, and either buccal for posterior teeth or labial for anterior teeth, with the correct options being a) for posterior and d) for anterior teeth.
Step-by-step explanation:
Every tooth in the mouth indeed has five surfaces. The correct five surfaces of a tooth are: occlusal, which is the biting surface of premolars and molars; mesial, the surface of the tooth towards the midline of the face; distal, the surface facing away from the midline; lingual, which is the surface of the tooth adjacent to the tongue; and lastly, buccal for posterior teeth or labial for anterior teeth, referring to the surface of the tooth facing the cheeks (buccal) or lips (labial). Hence, the correct surfaces depend on whether we're discussing anterior or posterior teeth. For anterior teeth (incisors and canines), the correct answer is d) Labial, incisal, lingual, mesial, and distal. For posterior teeth (premolars and molars), the answer is a) Buccal, occlusal, lingual, mesial, and distal.
