Answer:
The correct answer would be (B) Proteins will not fit into the active site of the amylase enzyme.
Enzymes are biocatalyst which accelerates the rate of a biochemical reaction.
They are highly specific to their substrate.
This high specificity is obtained with the help of the active site.
Every enzyme has the active site in which a particular substrate can fit or bind.
Similarly, salivary amylase also contains an active site which is specific for the polysaccharides like starch.
Proteins are not able to fit or bind to this active site due to which they are digested through amylase.
