The correct answer is C) he used federal troops to enforce desegregation in Southern schools.
The action that President Kennedy took to benefit the Civil Rights movement was that he used federal troops to enforce desegregation in Southern schools.
On June 11, 1963, President John F. Kennedy sent the National Guard to the Alabama University campus in Tuscaloosa, Alabama, to end the blockade imposed by Alabam governor George Wallas. He did not want two black students to enroll in the University. He was a racist and did not support desegregation.
The other incident that made Kennedy intervene was in the University of Mississippi, at Oxford. President Kennedy instructed Attorney in General, Robert F. Kennedy, to send US Marshall to accompany black Meredith to campus in Oxford. So yes, the action that President Kennedy took to benefit the Civil Rights movement was that he used federal troops to enforce desegregation in Southern schools such as Alabama and Mississippi.
