Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The activity of an enzyme is pH-dependent. The activity of an enzyme is maximum at pH $=$ 7.4 (physiological pH). In fact, as pH is increased, the enzyme activity rises, reaches a maximum level and then falls off.
Change in pH affects the solubility of the enzyme in water.
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
