Regarding the Secretion of HCl in the Stomach

Regarding the secretion of HCl in the stomach,

A) Hydrogen ion is actively transported into the gastric lumen by ATPase pumps in the mucosal membrane
B) Hydrogen ion is actively transported into the lumen by secondary active transporters coupled to K ion
C) The pH of the blood leaving the area of the parietal cells is lower than normal
D) Both hydrogen ion is actively transported into the gastric lumen by ATPase pumps in the mucosal membrane and the pH of the blood leaving the area of the parietal cells is lower than normal are correct
E) Both hydrogen ion is actively transported into the lumen by secondary active transporters coupled to K ion and the pH of the blood leaving the area of the parietal cells is lower than normal are correct
