Answer:
B) It was a major achievement when it was declared "separate but equal" was unconstitutional.
Step-by-step explanation:
Prior to the Brown v. the Board of Education Supreme Court case in 1954, there was a a doctrine in American Constitution law known as "separate but equal". This doctrine allowed people to be segregated by race in public facilities such as schools, trains and bars, as long as the quality of service remained the same.
The Supreme Court in the Brown v. the Board of Education case, ruled that “separate educational facilities are inherently unequal.”
Therefore, the "separate but equal" doctrine which supported black and white students attending different public schools, was rendered unconstitutional.
