Correct answer: C — Submandibular gland

The submandibular gland contributes approximately 60-65% of unstimulated (resting) salivary flow. During stimulated salivation (e.g., eating), the parotid gland becomes the dominant contributor (up to 50%). The sublingual gland contributes approximately 2-5%, and minor salivary glands approximately 10%. This is clinically relevant because submandibular duct obstruction (sialolithiasis) can significantly reduce resting salivary flow.
