Answer:
The correct answer is A. The Voting Rights Act enforced the Fifteenth Amendment's guarantee of political rights for African Americans.
Explanation:
The Voting Rights Act of 1965, enacted during the government of the Democrat Lyndon Johnson, definitively guaranteed equality in terms of political rights between African-Americans and whites, allowing unrestricted access to the vote of African-Americans and leaving them on an equal footing with citizens whites, who already enjoyed this right.
Ultimately, this law only reaffirmed and enforced the provisions of the Fifteenth Amendment, ratified in 1870, which already guaranteed the constitutional right to vote for African-Americans, but which in fact had not been applied because of segregation.
