Solution

The correct option is B Pepsin
Pepsin is an enzyme that breaks down proteins into smaller peptides. It is produced in the stomach as pepsinogen an inactive zymogen which is later converted by the acidic pH of the stomach into active pepsin. It gets activated and shows maximum activity at pH 2.
So, the correct answer is option B.
