A. NO CHANGE B. Abbott: C. Abbott, whose D. Abbott;
The best answer is A. No punctuation is needed here between the noun ("Robert S. Abbott") and the prepositional phrase describing that noun ("of the Chicago Weekly Defender"). The use here of the colon (Choice B) or the semicolon (Choice D) is not called for. Choice C incorrectly proposes setting this prepositional phrase off from the main clause and introducing it with the relative pronoun that expresses possession (whose).
