Explanation:

Step1: Analyze the graph

The optimal pH of an enzyme is the pH at which the rate of the enzyme - catalyzed reaction is the highest. Looking at the graph of "Rate of Enzyme - Catalyzed Reaction at Varying pH Levels", we need to find the peak of the curve.

Step2: Locate the peak pH

The x - axis represents the pH values. The peak of the curve (highest rate of reaction) occurs at pH = 8.

Answer:

A. 8
