Solution
The correct option is B Mucus The inner lining of the stomach is protected by the mucus secreted by mucoid cells present in the cardiac and pyloric regions of the stomach. It is a glycoprotein that covers the gastric mucosa by forming a thick layer and protects it from the action of gastric enzymes and HCl .
