o the supreme court ordered integration of the school.

The correct answer is the second one: President Eisenhower sent federal troops to protect the students.

Explanation:

The first statement doesn't relate to the question and the last statement refers to an event before the integration in the High School in Little Rock.

In 1954 the Supreme Court had ruled in Brown v. Board of Education case that segregation in public schools was unconstitutional.

So in 1957, the black movement decided to test the decision by registering nine black students in the Central High School in Little Rock, Arkansas. Governor Faubus tried to stop the group from studying there by calling the Arkansas National Guard to prevent their entrance to the school.

A few days later President Eisenhower sent in federal agents and troops to escort the students into the school.

The black students were recruited by a member of the local NAACP (National Association for the Advancement of Colored People) and received counseling sessions to understand and to prepare for the beginning of the school year and to know how to act on possible hostile situations inside the school.
