Answer: D. helps in digestion
Explanation: Gastric juice in the stomach contains HCL which creates an acidic condition(pH1.5-2.0) which is optimal for the action of enzymes in the stomach. HCL stops the activity of salivary amylase & helps to kill bacteria in food. It doesn’t help in digestion cuz it is not an enzyme.
