Solution

The correct option is A Oxyntic cell in human stomach secretes proenzyme, pepsinogen & trypsinogen
Parietal cells also known as the oxyntic cells are the stomach epithelium cells which secrete gastric acid. Parietal cells produce gastric acid in response to histamine acetylcholine and gastrin. Pepsinogen, proenzyme and trypsinogen are secreted by the chief cells in the oxyntic glandular area.
So, option A is the correct option.
