Use the excerpt below to answer the question that follows.
"In every government there are three sorts of power: the legislative; the executive in respect to things dependent on the law of nations; and the executive in respect to matters that depend on the civil law. When the legislative and executive powers are united in the same person, or in the same body of magistrates, there can be no liberty."
— Baron de Montesquieu, The Spirit of the Laws, 1748
Which specific feature of the U.S. Constitution most directly reflects the principle Montesquieu argues for in this passage?
Explanation: Montesquieu explicitly argues that combining legislative and executive powers in the same person or body destroys liberty — making separation of governmental functions essential to freedom. The Constitution's three-branch structure (Articles I, II, III) directly implements Montesquieu's argument. The Preamble (Choice A) addresses popular sovereignty, not branch separation. The Bill of Rights (Choice C) protects individual rights but is not the structural response to Montesquieu's argument. The Supremacy Clause (Choice D) addresses the hierarchy of law, not the separation of governmental functions. This question tests a confirmed FLDOE exam type — connecting an Enlightenment philosopher's primary source argument to a specific constitutional feature.
