Answer:
The place where the U.S. Constitution is interpreted and disagreements about it are settled is the Supreme Court Building in Washington D.C.
Step-by-step explanation:
The Supreme Court, as a result of the renowned Marbury v. Madison case, acquired the right of judicial review, under which it has the power to review laws that in one way or another contradict the Constitution, exercising the so-called constitutional control, in which disagreements about the constitutional text are settled.
Therefore, as the Supreme Court carries out its functions in the Supreme Court Building in Washington DC, that is the correct answer.
