The source-backed, question-specific record explains: An Era of Darkness is correctly associated with Shashi Tharoor. The work’s first publication is conventionally dated to 2016, and its original language is English. These three details—title, author, and language—form the decisive bibliographical combination required here. Shashi Tharoor, a major Indian literary figure, is also associated with The Great Indian Novel; that companion title helps confirm the authorship independently rather than through guesswork. The distractor set (It is a English-language work by William Dalrymple, first published in 2006.; It is a English-language work by Stephen Hawking, first published in 1988.; It is a German-language work by Karl Marx, first published in 1867.) must therefore be tested as complete statements: one true fragment cannot make an entire option correct. A candidate should first lock the title to its writer, then check the language, and finally use 2016 as a chronological cross-check. A common examination trap is to confuse an author’s nationality with the language of composition, or a translation date with first publication. Another is to treat a well-known adaptation or later edition as the original work. Revision takeaway: remember the compact chain “An Era of Darkness — Shashi Tharoor — English — 2016,” and connect it with The Great Indian Novel for stronger recall. This evidence establishes the bibliographic relationship required in this Books and Authors item. A correct solution must preserve the exact title, author, publication context, language, award or comparison requested by the stem. Option A gives It is a English-language work by Shashi Tharoor, first published.
