The correct answer is the judicial branch.
The judicial branch consists of the US Supreme Court. The US Supreme Court was given the ability to interpret laws following the Marbury vs. Madison Supreme Court case. In this case, it was determined that the Supreme Court had the power of judicial review. This concept gave the Supreme Court the power to interpret the laws.

This important case resulted in the judicial branch becoming a powerful third branch of the federal government.
