Correct option is B)

Parietal cells secrete HCl which act as an activator for enzymes pepsinogen. This enzyme helps in the digestion of protein. Hence, if for some reason the parietal cells of the gut epithelium become partially non-functional, proteins will not be adequately hydrolyzed by pepsin into proteases and peptones.

Hence, the correct answer is (B)
