Man has ________ pairs of salivary glands.

The correct answer is: A. 3

Man has three pairs of salivary glands: parotid, submandibular, and sublingual.

• The parotid glands are the largest salivary glands and are located in front of the ears.
• The submandibular glands are located under the jaw.
• The sublingual glands are located under the tongue.

The salivary glands produce saliva, which helps to moisten and lubricate food, and also contains enzymes that begin the process of digestion.
