judged are elected at the federal level, and the system for selecting judges differs by state government.

The correct answer is B. Judges are appointed at the federal level, and the system for selecting judges differs by state government.

Explanation:

In the U.S. court system, there are two main levels the federal level and the state level. In the case of the federal level, judges are usually appointed by the President of the U.S.  with the approval of other entities such as the senate. The judges appointed by the President are part of the federal level, which means they act at a national level and serve until their resignation, death or impeachment.

On the other hand, judges at state or local level can be either appointed or elected mainly based on specific parameters in each state, which means there is not a unified method or parameters for selecting judges at this level. Thus, the true statement is "Judges are appointed at the federal level, and the system for selecting judges differs by state government".

Explanation:

The U.S. judiciary features a dual court system comprising a federal court system and the courts in each of the fifty states. On both the federal and state sides, the U.S. Supreme Court is at the top and is the final court of appeal.
