Which of the following types of jurisdiction exists when there is a federal question for the court to decide?

Subject matter jurisdiction refers to the authority of a court to hear cases of a particular type or cases relating to a specific subject matter. When a case involves a federal question, which encompasses issues arising under the U.S. Constitution, federal laws, or treaties, it falls under the category of federal subject matter jurisdiction. This means that the federal courts have the right to hear and decide the case based on the nature of the legal issue involved.

In this context, federal question jurisdiction does not rely on the parties being from different states, unlike diversity of citizenship jurisdiction, which is based on the parties being from different states and the amount in controversy exceeding a certain threshold. In rem jurisdiction concerns the power a court has over property within its territory, while personal (in personam) jurisdiction refers to a court's authority over the parties involved in the litigation. Therefore, the correct type of jurisdiction pertaining to federal questions is indeed subject matter jurisdiction.
