Hint: The cells of salivary glands synthesize molecules and empty it into our mouth through openings referred to as ducts. secretion helps with swallowing and chewing. It can even help prevent infections from developing in our mouth or throat. This enzyme is named salivary amylase.

Complete answer: 
Salivary enzyme could be a glucose-polymer cleavage accelerator that's synthesised by the glands. It contains a low portion of the overall enzyme excreted, which is usually synthesised by the duct gland. Amylases digest or convert starch into smaller molecules, ultimately yielding a disaccharide that successively is cleaved into 2 aldohexose molecules by maltase. Starch contains a large portion of the everyday human diet for many nationalities. 
Hence generally amylase enzymes convert starch into glucose i.e. into simple sugars.
So, option (B) is the correct answer.

Note: In digestion mainly carbohydrates are converted into simple sugar like glucose suddenly in the first step through the salivary enzyme called salivary amylase. As protein and lips are more complex than sugar so it is not generally digestible by salivary amylase. Parotid, submandibular and sublingual glands help in the section of Salivary amylase.
