Correct answer: B — Parotid gland
**A. Parotid gland** is correct. Serous acini produce a watery, protein- and enzyme-containing secretion; the parotid is composed of serous acini and is the major salivary gland most clearly associated with serous saliva. The **submandibular gland** is a mixed seromucous gland, so it cannot be classified as predominantly serous in this SBA. The **sublingual gland** is predominantly mucous, producing a more viscous, mucin-rich secretion. Minor salivary glands in the **palate** are chiefly mucous, while those of the **lip** are generally mixed rather than purely serous. Thus, among the options, only the parotid gland is the unequivocal serous-predominant gland.
