Answer:
B
Step-by-step explanation:
Nucleic acid digestion yields nucleotides, whereas protein digestion yields amino acids. Both digestive processes require the presence of Hydrochloric acid to lower the pH. Hydrochloric acid popularly described as HCl contributes in both protein and nucleic acid digestion by supplying hydrogen ions which in turn activate pepsinogen, which in turns form pepsin necessary for digestion.
