Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
If HCl is not secreted, digestion of proteins in the stomach will be impaired because HCl provides the necessary acidic pH which is required for function of pepsin and renin. Inactive pepsinogen is hydrolysed into active pepsin by HCl and thus HCl also denatures many food proteins.
