Answer:
The correct answer is D. The Three-Fifths Clause in the US Constitution gave the white South greater power in national affairs than the size of its free population warranted.
Step-by-step explanation:
The Three-Fifths Clause was inserted in Article 1, Section 2 of the Constitution. The calculation of the population of each state originally included all "free persons", and three-fifths of slaves. Given this treatment given to slaves, attempts were made to limit the rules of the states regarding the property exercised over them, reducing their participation in the House of Representatives. This was known as the "three fifth compromise." The Fourteenth Amendment changed this measure, eliminating the three fifth clause, as slavery was abolished after the Civil War.
