Answer:
Option A. Poll tax is an example of a voting requirement that was used to prevent African Americas from voting during the Jim Crow era.
Step-by-step explanation:
The Jim Crow era comprised all of the laws that enforced racial segregation in the United States from the end of Reconstruction in 1877 until 1965 were they were prohibited. After the Reconstruction Era, many of the Southern states imposed a poll tax law, which required all aspiring voters to pay a tax as a prerequisite. This was made in an effort to keep African American voters away from the polling station, as the majority of them were immersed in poverty and did not have the means to afford the tax.
