Answer:
D. Fifteenth Amendment protected the right of former slaves to vote
Explanation:
The Fifteenth Amendment was one of the three amendments enacted after the American Civil War to ensure equality for African Americans. This Amendment, ratified on February 3, 1870, protects the right of former male slaves, now US citizens under the 14th Amendment, to vote. In other words, the 15th amendment established that voting rights could not be denied based on race, color or previous condition of servitude.
