Answer: c. Phoenix has water rights associated with its agricultural activities
Step-by-step explanation:
Phoenix is located in an area that receives little rainfall and is more prone to drought and as they keep growing to unsustainable numbers, the pressure on the Colorado river has increased massively.
Phoenix does not need to worry about water supply for the foreseeable future however because it has substantial surface water rights that are linked to its agricultural activities that will help them meet their demand.
