The correct option is A Pepsinogen → Zymogenic cells
Chief cells or Peptic cells (Zymogen cells) are usually basal in location in stomach wall and secrete gastric digestive enzymes as proenzymes or zymogens; pepsinogen and prorenin. The oxyntic or parietal cells in stomach secrete the acid hydrochloric acid. The acinar cells in pancreas secrete digestive enzymes. The goblet cells secrete mucous. The goblet cells are widely distributed throughout the alimentary canal. The saliva contains amylase called ptyalin.
