Correct answer: E — Sublingual gland

The correct answer is E, the sublingual gland. It occupies the sublingual space immediately beneath the floor-of-mouth mucosa, lateral to the genioglossus and superior to the mylohyoid, which forms its principal inferior muscular relation. The superficial part of the submandibular gland lies mainly inferior to the mylohyoid in the submandibular space. Its smaller deep part curves around the posterior free border of the mylohyoid and lies farther posteriorly in the floor of the mouth. The parotid gland is situated in the parotid region, while minor salivary glands are dispersed within the oral mucosa rather than forming a single gland in this anatomical space.
