Answer: 1. Digestion of disaccharides

Key idea: Salivary amylase digests starch, but no salivary enzyme digests disaccharides.

Salivary amylase digests complex carbohydrates (starch) to maltose, so option 3 is a function.
Lysozyme in saliva controls bacteria, so option 2 is a function.
Mucus lubricates the oral cavity, so option 4 is a function.

Disaccharides are digested in the small intestine by maltase, sucrase and lactase. So option 1 is not a function of saliva.
