Answer:
A. It prohibited the use of poll taxes in elections, protecting the rights to vote of the poor.
Step-by-step explanation:
Poll taxes represent the amount of money that people need to pay in order to cast out their votes during the election.
Many poor families in the past choose to not use their right to vote because they simply couldn't afford it. This was a really good way for the government to prevent the poor people from electing a representative that could help them get out of their situations.
Poll taxes existed in United States in 1890 and only eliminated after huge pressure from the civil right movements in 1964.
