Dear student.

The correct term is ptyalin.

The correct answer is A. Ptyalin

Ptyalin is an enzyme found in saliva that breaks down the insoluble starch found in foods into smaller, soluble sugar fragments. This is another name for the 'amylase' found in saliva, known as salivary amylase. This particular type of amylase is found only in humans.

Rest all the options mentioned here are hormones.

Regards.
