Which jurisdiction arises when parties are citizens of different states and the amount in controversy exceeds a threshold?

• A. Diversity jurisdiction
• B. Federal question jurisdiction
• C. Concurrent jurisdiction
• D. Removal

Answer: (A)

Diversity jurisdiction is triggered when parties are citizens of different states and the amount in controversy exceeds the statutory threshold. This form of federal subject matter jurisdiction requires complete diversity—every plaintiff must be from a different state than every defendant—and an amount in controversy above the limit (currently $75,000). When these conditions are met, a federal district court can hear the case even if the claims are purely state-law. This differs from federal question jurisdiction, which exists when the claim itself arises under federal law; concurrent jurisdiction refers to cases that could be heard in either court, and removal is the process of moving a case from state court to federal court, not the basis for jurisdiction itself.
