To determine which enzyme would work best in a given organelle, we need to identify the enzyme that shows the highest activity within the relevant pH range of that organelle. We are provided with the activity levels of four enzymes across different pH ranges in the table.

Let's analyze the table step-by-step:

1. pH 2-4:
- Enzyme I: Inactive
- Enzyme II: Inactive
- Enzyme III: High
- Enzyme IV: Low

Since Enzyme III has high activity in this pH range, it would be the best choice for an organelle with a pH of 2-4.

2. pH 4-6:
- Enzyme I: Inactive
- Enzyme II: Low
- Enzyme III: Low
- Enzyme IV: High

In this pH range, Enzyme IV exhibits high activity and would be the best choice.

3. pH 6-7:
- Enzyme I: Low
- Enzyme II: High
- Enzyme III: Inactive
- Enzyme IV: Low

For the pH range of 6-7, Enzyme II has high activity and would be the most effective enzyme.

4. pH 7-9:
- Enzyme I: High
- Enzyme II: Low
- Enzyme III: Inactive
- Enzyme IV: Inactive

Here, Enzyme I has high activity and would work best in this pH range.

5. pH 9-11:
- Enzyme I: Low
- Enzyme II: Inactive
- Enzyme III: Inactive
- Enzyme IV: Inactive

Although Enzyme I is the only enzyme with any activity in this range (low), it is not the ideal choice for high activity.

By analyzing all the pH ranges, we see that Enzyme III stands out with high activity in the pH range of 2-4, where other enzymes do not perform well. Therefore, the enzyme that would work best in the organelle, considering we need high activity at its specific pH, is:

C. Enzyme III
