During the surgical removal of the submandibular salivary gland, which of the following nerves is least likely to be damaged?

Explanation

The lingual nerve, mandibular branch of the facial nerve, and hypoglossal nerve are all anatomically close to the submandibular gland and are at risk during its excision. In contrast, the spinal accessory nerve is located far from this surgical site and is unlikely to be injured during the procedure.
