Answer:
B . It struck down segregation laws as unconstitutional.
Explanation:
In the Brown v. Board of Education of Topeka case (1954), the Supreme Court struck down segregation laws which had been so common in the U.S. so far, as it determined that “separate but equal” schools and facilities were unjust, unequal, and they were a form of discrimination that instilled a sense of inferiority to African Americans children, and therefore, it violated the guarantee of equal protection of the laws to all citizens, regardless of their race, stated in the 14th Amendment.
