In what sense does Devlin compare Catholics of Northern Ireland to African Americans in their civil-rights struggle? A. economically

B. psychologically

C. racially

D. religiously

The correct answer is B.

Bernadette Devlin was an Irish politician and Civil Rights leader. When she compared the fight of Catholics in North Ireland with the Civil Rights Movement of the African Americans of the US, she did so taking into account that these two groups were feeling like second class citizens in their respective countries and how both took a step forward to fight for their rights.

These two movements were different in terms of the feature that generated the discrimination, in case of the Catholics it was due to religious differencies but for African Americans the causes were racial. Anyway both groups felt very similarly the discrimination, this is why Devlin compared the physicological dimension of the two movements.
