b. Proteins that are consumed in the diet are absorbed as individual amino acids following digestion.

Explanation:

Protein digestion begins in the stomach by enzyme called pepsin. Pepsin is secreted by pancreas of the internal body in the form of inactive enzyme called pepsinogen. However, due to the acidic nature (Lower pH), pepsin is activated and this Pepsin digests the protein into the polypeptides.

Now, these polypeptides move to the duodenum where the pH is high that is basic in nature. However, in the small intestine, enzymes some of the such as aminopeptidase and dipeptidase digest the dipeptides or tripeptides into amino acids.

Hence the correct answer is B.
