The correct answer is B) It outlawed voting discrimination based on race.
The 15th amendment made it so that newly freed black men could vote in elections. This era of Reconstruction resulted in a significant amount of black men voting and being elected to office in the Southern states. However, this new found political freedom would not last thanks to the end of Reconstruction in 1877. After this time, Southern states implemented barriers to voting like poll taxes, grandfather clauses, and literacy tests to prevent black men from voting.
