Following a mid-air collision, a passenger in one of the planes, a citizen of State A, sued the Federal Aviation Administration in federal court under the Federal Tort Claims Act, alleging negligence on the part of its air traffic controllers. The passenger also named the pilot of the other plane, a citizen of State A, as a defendant for a claim based on state law negligence. The pilot moves for dismissal as to him. If the court grants the motion to dismiss, what is the most likely reason?
A) The Federal Rules of Civil Procedure do not permit joinder under these facts.
B) There is no basis for federal subject matter jurisdiction.
C) The court has declined to exercise supplemental jurisdiction.
D) The claim against the pilot is not sufficiently related to the claim against the Federal Aviation Administration.
