Chief cells are known for producing and secreting pepsinogen, an inactive enzyme that is activated by the acidic environment of the stomach to form pepsin. Pepsin plays a crucial role in the digestion of proteins. The secretions of chief cells have a pH range between 2.0 and 3.0, reflecting the acidic nature of the gastric environment necessary for optimal pepsin activity. Hence, the correct answer is option 1.
