The correct answer is A. During Reconstruction, some southern whites passed laws (called Jim Crow Laws) denying blacks voting rights.

Explanation:

The Jim Crow Laws were state and local laws promulgated by the white state legislatures, that at the time were dominated by the democrats after the period of Reconstruction. These laws advocated the racial segregation in all public facilities by de jure mandate under the slogan "separate but equal" and applied to African-Americans and other non-white ethnic groups in the southern states of the United States. In reality, this led to treatment and accommodation being generally inferior to those insured for American whites, systematizing a number of economic, educational and social disadvantages.

Some examples of Jim Crow Laws were segregation in public schools, public places, public transportation and the segregation of bathrooms and restaurants; In addition, there were also sources of drinking water for whites and blacks. The US military was also segregated.

School segregation supported by the government was declared unconstitutional by the Supreme Court in 1954 based on the ruling in Brown v. Board of Education. In general, the rest of the Jim Crow Laws were derogated by the Civil Rights Act of 1964 and the Voting Rights Act of 1965.
