In humans three types of chief cells are found, one of which is present in the stomach and thus are called gastric chief cells.
The gastric chief cells are involved in the digestion of proteins present in the food by producing pepsinogen enzymes in its inactive form which gets activated in the presence of acid produced by the parietal cells.
Since the pepsinogen is produced to digest the proteins and not to prevent the erosion caused by the acid inside the chief cells therefore, false is the correct answer.
