If one of them (A, B or C) is better than the underlined part, indicate your response on the Answer-sheet against the corresponding letter A, B or C. If none of these substitutions improves the sentence, indicate D as your response on the Answer-sheet. Thus a "No Improvement" response will be signified by the letter D.
