We conclude that in the field of public education the doctrine of “separate but equal” has no place. Separate educational facilities are inherently [by their nature] unequal.

In which case did the Supreme Court issue the above opinion?

A. Plessy v. Ferguson
B. Brown v. Board of Education
C. Dred Scott v. Sanford
D. Marbury v. Madison

B. Brown v. Board of Education

The Supreme Court issued the opinion that "separate but equal" has no place in the field of public education in the case of Brown v. Board of Education.

To find the answer, you can follow these steps:

1. Understand the concept of "separate but equal": The phrase "separate but equal" refers to the doctrine that allowed for racial segregation in public facilities, including schools, as long as the separate facilities were considered to be equal in quality.

2. Look for the case related to racial segregation and public education: The question asks about the case in which the Supreme Court issued the opinion against the "separate but equal" doctrine in public education. Among the given options, the only case related to racial segregation and education is Brown v. Board of Education.

3. Eliminate the incorrect options: The other options, Plessy v. Ferguson, Dred Scott v. Sanford, and Marbury v. Madison, are not directly related to the issue of racial segregation in public education. Plessy v. Ferguson upheld racial segregation in public facilities, Dred Scott v. Sanford dealt with slavery and the rights of African Americans, and Marbury v. Madison established the principle of judicial review.

Therefore, the correct answer is B. Brown v. Board of Education.

The Supreme Court issued the opinion that separate educational facilities are inherently unequal in the case of B. Brown v. Board of Education.
