Answer 1

The trigeminal nerve, specifically the mandibular branch, is responsible for the sensation in the lower teeth and enters the mandibular foramen.

Step-by-step explanation:

The correct answer is (b) Trigeminal nerve, body.

The trigeminal nerve is responsible for the sensation of the face and controls the muscles of chewing. It has three branches: ophthalmic, maxillary, and mandibular. The mandibular branch of the trigeminal nerve provides sensory innervation to the lower teeth and enters the mandibular foramen, which is located on the medial side of the mandibular ramus.
