Explanation:

Step1: Identify the percentages

The percentage of water returned to the sea unused is 24%, and the percentage used by people is 7%.

Step2: Calculate the ratio

To find how many times more water returns to the sea unused than is used by people, we divide the percentage of water returned to the sea unused by the percentage used by people: $\frac{24\%}{7\%} \approx 3.43$. This is approximately three times.

Answer:

B. About three times as much
