c. separate but equal policy was wrong
d. the government must provide loans to low-income college students

C?

can you please tell me if C is correct?

Yes. C is correct.

Correct! The answer is C. The Supreme Court ruled in Brown v. Board of Education in 1954 that the "separate but equal" policy, which had allowed racial segregation in public schools, was unconstitutional. This landmark decision declared that racial segregation in public education violated the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution. The case was a significant step in the civil rights movement and played a crucial role in desegregating schools in the United States.

To arrive at this answer, you would need to have a basic knowledge of the historical context surrounding the Brown v. Board of Education case. Understanding the purpose of the case and its impact on civil rights in the United States would help you to correctly identify option C as the correct answer.
