The correct answer is: Since segregation laws did not provide equal protections or liberties to non-whites, the ruling was not consistent with the 14th Amendment.
Indeed, segregated school facilities for African Americans were usually heavily underfunded and understaffed with regards to facilities for White Americans. They were also usually very far from the children homes and the schools bus transportation system was very substandard. Research conducted by the Supreme Court Justices and by the anti-segregationist litigants had conclusive evidence of this.
