Freedom Riders were civil rights workers who took bus trips through southern states in 1961 to protest what?

• A. Illegal bus segregation.
• B. Prohibition.
• C. Labor unions.
• D. School desegregation.

Answer: (A)

Riding interstate buses to challenge segregation in travel is what the Freedom Riders were doing and what they were aiming to change. They went through Southern states to highlight that segregated facilities and seating on interstate transportation were illegal and should be enforced, drawing national attention to the need for federal action to desegregate public accommodations across state lines. The focus was on illegal bus segregation in interstate travel, not on prohibitions, labor unions, or school desegregation, which is why this option fits best.
