Answer: D. Digestion increases as the volume of the enzyme increases.
Explanation:
Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster. 
Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.

Which is true about enzymes is: enzymes increase the rate of reactions by lowering the activation energy barrier.
Enzymes are chemical compounds in the form of proteins that act as biocatalysts which function to speed up reactions.
Enzymes work specifically, that is, they can only work on certain substrates by adjusting the shape of the substrate. Enzymes sensor with molecules for substrates to produce compounds through organic chemical reactions that require energy. Some of the reactions assisted by enzymes such as the breaking of large molecules into small ones or the binding of molecules into new molecules. Enzymes can do that because of the influence of the activation energy that every chemical reaction has. 
Activation energy is the energy required to break down the reactants. The role of enzymes is to lower the activation energy limit needed to start reactions.
