Solution

The correct option is B Pineapple
The enzymes shows maximum activity at an optimum pH. The range of optimum pH is specific for a particular enzyme. According to the given graph, pineapple extract was effective from pH 2 to pH 12 i.e., extremely acidic pH to extremely alkaline pH which clearly indicates the optimum functional range of enzymes in the juice.
So, the correct answer is option B.
