Only book D is simultaneously (i) new, (ii) a law report, and (iii) red-covered: the ‘new’ condition limits choices to D or F; among these, only D is a law report and it has a red cover (B C E are blue). Hence option D. ([gktoday.in](https://www.gktoday.in/analysis-of-upsc-civil-services-2010-gs-paper-part-ii/))
