The correct answer is C. White voting officials administered difficult literacy tests to African American voters
Step-by-step explanation:
In politics, disenfranchisement occurs as a person or group of people are not allowed to vote usually due to policies, practices or requirements that prevent them from voting. In the U.S. this occurred with African Americans after the Reconstruction as laws and requirements were created in the South to stop African Americans from voting, this included asking them to pass literacy tests, understanding tests and also to pay poll taxes.
In the case of tests, these were only required to African Americans and in most cases, they were too difficult for them especially as they were not given education or were applied by white people who could change the results. Considering this, the statement about the disenfranchisement of African Americans that is true is "white voting officials administered difficult literacy tests to African American voters".
