Answer: The 24th Amendment prohibited the use of the poll tax. Black protestors put pressure on legislators to abolish the polls tax through boycotts and sit-ins.
Explanation: This amendment was an extension of the Voting Rights Act of 1965.
The correct answer is C.
The 24th Amendment to the US Constitution was ratified in 1964 and it banned the usage of poll taxes in Southern States, as these were discriminatory and prevented the most humble sectors of the population and minorities (black citizens) from voting.
As most of the actions undertaken during the Civil Rights Movement, public support was gained by non-violent methods, such as sit-ins.
