If you have just eaten a mean high in complex carbohydrates, amylase is the enzyme that will help to digest the meal. 

Amylase is an enzyme that help to digest the complex carbohydrates present in the meals, hence option B is correct.

Amylase is an enzyme or particular protein that aids in the breakdown of carbohydrates. Pancreas and salivary glands produce the majority of the amylase that is found in your body. It's normal to have a tiny quantity of amylase in blood and urine.

Glucose is created through your body's breakdown of carbs. The primary source of energy for the cells, tissues, and organs in your body is glucose, sometimes known as blood sugar.
