An American city has a high crime rate. A citizen of that city wants to own a firearm so he can protect his property. The city does not allow residents to own certain types of firearms. The citizen files suit, claiming that his right to own a firearm is protected by the Bill of Rights. The Supreme Court rules in favor of the citizen and strikes down the city’s ban on certain types of firearms. In which of the following ways is the outcome of the scenario explained by the doctrine of selective incorporation?

- The city was unable to ban firearms because it lacked the power of a state.
- The Supreme Court ruled that the Second Amendment is enforceable upon the states.
- The citizen was successful because he argued that the city was discriminating against him.
- The federal statutes on firearms took precedence over stricter state and city laws that limited ownership.
