## Step 1<br />The problem is asking us to identify the constitutional basis for the United States Supreme Court decision in the case of Brown v. Board of Education of Topeka. This case is a landmark in the history of civil rights in the United States, as it declared state laws establishing separate public schools for black and white students to be unconstitutional.<br /><br />## Step 2<br />The options provided are different amendments to the United States Constitution. We need to identify which amendment was the basis for the Supreme Court's decision in this case.<br /><br />## Step 3<br />The Supreme Court's decision in Brown v. Board of Education of Topeka was based on the Fourteenth Amendment's guarantee of equal protection. This amendment guarantees that no state shall "deny to any person within its jurisdiction the equal protection of the laws."<br /><br />## Step 4<br />The Supreme Court found that the segregation of public schools based on race was a violation of this guarantee, as it created inherently unequal educational opportunities for black and white students.
