Which of the following can you correctly infer from the graph about how the pH affects the enzyme's role in the target chemical reaction?

There is a specific pH range in which the enzyme effectively lowers the reaction's activation energy.

Increasing the pH makes it easier for the enzyme to lower the activation energy of the target reaction.

As the pH increases, the activity of the enzyme to lower reaction activation energy is decreased.

The enzyme will not assist the chemical reaction at a pH that is below 6 or above 12.
