Verified step by step guidance

Begin by identifying the primary function of each structure listed in the problem. The esophagus is a muscular tube that transports food from the mouth to the stomach, and does not produce digestive enzymes.

Next, consider the salivary glands. These glands are located in the mouth and are responsible for secreting saliva, which contains digestive enzymes such as amylase that begin the process of breaking down carbohydrates.

Examine the large intestine. Its main function is to absorb water and electrolytes from indigestible food matter and to form and store feces. It does not produce digestive enzymes.

Consider the gallbladder. This organ stores bile produced by the liver, which aids in the digestion of fats, but it does not produce digestive enzymes itself.

Conclude that the salivary glands are the correct answer, as they are the only structure among the options that actively produce and secrete digestive enzymes.
