Final answer:
A racial discrimination case against an employer that is the federal government would be heard in a federal district court because it involves a violation of federal law and the federal court system has jurisdiction over such civil matters.
Step-by-step explanation:
A person with a racial discrimination case against his employer, which is the federal government, would have that case heard in a federal district court.
This type of case involves a civil violation of federal law and thus falls under the jurisdiction of the federal court system. The federal district courts are the trial courts of the national court system, handling both civil and criminal matters that involve federal law or constitutional rights.
In this case, since the federal government is the employer, the matter directly involves federal law and would not be reviewed by the state courts. The district court is often the starting place for federal litigation, after which cases can be appealed and potentially reach higher courts, such as the U.S. courts of appeals, or even the U.S. Supreme Court, though the latter is rare.
Therefore answer is B) Federal district court.
