The correct answer is B) express their opposition to the Brown ruling

Members of Congress signed the "Southern Manifesto" to express their opposition to the Brown ruling.

The Southern Manifesto was written during February and March 1956. It was the Declaration of Constitutional Principles. Members of the Congress wrote the document as an opposition to racial integration in public places. Those members of Congress opposed the Supreme Court decision in the case of Brown v. Board of Education of Topeka. The Supreme Court unanimously decided that racial segregation in public schools was unconstitutional.
