Solution

The correct option is A HCl
Saliva contains an enzyme called salivary amylase (ptyalin). Salivary amylase is inactivated in the stomach by gastric acid ( $H C l$ ). In gastric juice pH 3.3, ptyalin gets inactivated in 20 minutes after entering into the stomach, as its optimum pH is basic.
So, the correct answer is option A.
