Answer:

D. The starches have been partially broken down.

Explanation:

Your saliva has salivary amylase, an enzyme that breaks down starch into smaller glucose monomers. Thus, by the food reaches your tummy, some of the starch has been broken down. Protein and fats are primarly broken in stomach and food also becomes acidic in stomach.
D. The starches have been partially broken down. Yes because your saliva has a protein that breaks down starches.
