Answer:
C.
John F. Kennedy
Explanation:
"During his presidential campaign in 1960, John F. Kennedy had promised the most ambitious domestic agenda since the New Deal: the “New Frontier,” a package of laws and reforms that sought to eliminate injustice and inequality in the United States. But the New Frontier ran into problems right away: The Democrats’ Congressional majority depended on a group of Southerners who loathed the plan’s interventionist liberalism and did all they could to block it.
[...] In general, the federal government stayed out of the civil rights struggle until 1964, when President Johnson pushed a Civil Rights Act through Congress that prohibited discrimination in public places, gave the Justice Department permission to sue states that discriminated against women and minorities and promised equal opportunities in the workplace to all. The next year, the Voting Rights Act eliminated poll taxes, literacy requirements and other tools that southern whites had traditionally used to keep blacks from voting."
