Explanation:
Detailed explanation-1: -The stomachs of most vertebrates operate at an acidic pH of 2 generated by the gastric H+/K+-ATPase located in parietal cells. The acidic pH in stomachs of vertebrates is believed to aid digestion and to protect against environmental pathogens.
Detailed explanation-2: -The normal volume of the stomach fluid is 20 to 100 mL and the pH is acidic (1.5 to 3.5).
Detailed explanation-3: -So, the correct answer is ‘stomach’.
