Answer:
B) the EPA's decision takes precedence.
Step-by-step explanation:
The environmental protection agency (EPA) is a federal government agency, and all federal government's regulations, policies and laws are hierarchically superior to state and municipal laws and regulations. In a similar way, state laws and regulations are hierarchically superior to municipal laws and regulations.
The highest law of the land is the US Constitution but it doesn't include specific laws or regulations, it states rights and obligations of the citizens, and assigns powers and responsibilities to different government branches.
