An unanswered Constitutional question about the judicial branch is how to create lower federal courts.

Answer; B
how to create lower federal courts

An unanswered Constitutional question about the judicial branch is how to create lower federal courts.

Explanation;
According to the constitution the power to interpret the law of the United States will be held by the U.S. Supreme Court, and the lower federal courts. Inferior courts will be created by Congress from “time to time.” The Constitution itself created only the Supreme Court, but allowed Congress to create other, inferior (lower) courts over time.
