Hey mate if you know the answer then why did you post this question ???

Answer 2

Option B (reservoirs) would be the right option. A further explanation is given below.

Explanation:

• A reservoir has become a man-made wetland or maybe even a massive number of waterways. Another lot of individuals still think of a somewhat reservoir as anything other than a lake but instead would perhaps that much utilize terms interchangeably.
• This same major difference, that being said, would be that the storage tanks were also man-made and unnatural, whereas the lakes were already contained natural watersheds.

All those other choices available are not connected to the circumstance in question. So the above alternative is the right one.
