{'enzymes': [3, 0, 6, 3], 'human saliva': [0, 0, 0, 1], 'pepsin': [10, 0, 3, 2], 'trypsin': [1, 0, 0, 0], 'ptyalin': [0, 0, 1, 1], 'rennin': [2, 1, 0, 1]}
The correct answer is option 3: Ptyalin.
Trypsin, option 1, is an enzyme found in the small intestine and helps with the digestion of proteins.
Pepsin, option 2, is an enzyme found in the stomach and is responsible for the digestion of proteins.
Rennin, option 4, is an enzyme found in the stomach of infants and is involved in the digestion of milk.
Ptyalin, option 3, is the correct answer as it is an enzyme found in human saliva. Ptyalin, also known as salivary amylase, plays a vital role in the digestion of carbohydrates. It breaks down complex carbohydrates, such as starch, into simpler sugars during the initial stages of digestion in the mouth.
Therefore, the correct answer is option 3: Ptyalin.
