Mark Trenchant owned a store in Alabama in which he sold guns. His store had been in operation for ten years and was located one block from Eastwood Elementary School. This year a federal statute was enacted that made it a crime to sell guns within one mile of any primary school. Both the Alabama common law and an Alabama state statute, enacted five years ago, gave Trenchant the right to sell guns at his current location. Trenchant continued to operate his store and was taken to court over the issue. The court will most likely find Trenchant:

a$.$ guilty under the federal statute.

b$.$ not guilty because Alabama common law has been in existence longer than any other relevant source of law.

c$.$ not guilty because the Alabama state statute was enacted prior to the federal statute.

d$.$ not guilty because this is a civil issue.
