I really need help on this plzzz help me

A writer wants to make the following claim:

Because of the lessons we have learned about careful water use, restrictions on the watering of lawns in Springdale should continue even after the drought ends.

Which of the following would provide the most convincing support for this claim?

-Interviews with people who water their lawns too much and do more harm than good

- Evidence that restrictions effectively save significant amounts of water

-A claim by the homeowners' association that the restrictions are in the best interests of the neighborhood
