The salivary gland that produces a serous secretion containing large amounts of amylase is the parotid gland.

Here's why:

* Serous secretion: This type of secretion is watery and contains enzymes, which are crucial for digestion.

* Amylase: This enzyme breaks down starch into simpler sugars.

* Parotid gland: This gland is located near the ears and produces a high volume of serous saliva rich in amylase.

While the other salivary glands (submandibular and sublingual) also produce saliva, they are more mixed in their secretions, containing both serous and mucous components.
