The correct answer is B. Exclusive jurisdiction.

To arrive at this answer, we need to understand the concept of jurisdiction and the different types of jurisdiction that exist.

Jurisdiction refers to the authority and power of a court to hear and decide a case. In the United States, there are two main types of jurisdiction: federal jurisdiction and state jurisdiction. The federal courts have jurisdiction over cases involving federal laws, the Constitution, and certain other specific subject matters.

In this question, the trial of a person charged with a federal crime or a suit involving the infringement of a patent or a copyright, or any other matter arising out of an act of congress falls under the jurisdiction of the federal courts. This means that only the federal courts have the authority to hear and decide such cases, and no other court (such as state courts) has the power to do so.

Therefore, the correct answer is B. Exclusive jurisdiction, as the federal courts have exclusive authority over cases involving federal crimes or matters arising out of an act of congress.
