Answer

The first enzyme to mix with food in the digestive tract is C. Amylase.

Explanation

Amylase is an enzyme that initiates the process of carbohydrate digestion. It is present in saliva and begins breaking down starches into simpler sugars as food is chewed and mixed with saliva. This enzymatic activity continues in the stomach, although it may be inhibited by the acidic environment. Other options listed, such as pepsin (which digests proteins), cellulase (which breaks down cellulose), and trypsin (another enzyme that digests proteins but acts further along in the digestive tract), do not interact with food until later stages of digestion. Thus, amylase is indeed the first enzyme to engage with food during digestion.
