The verified answer to “Books and Authors question: Consider the pair Gunahon Ka Devta and Andha Yug. The source-backed, question-specific record explains: Gunahon Ka Devta is correctly associated with Dharamvir Bharati. The work’s first publication is conventionally dated to 1949, and its original language is Hindi. These three details—title, author, and language—form the decisive bibliographical combination required here. Dharamvir Bharati, a major Indian literary figure, is also associated with Andha Yug; that companion title helps confirm the authorship independently rather than through guesswork. The distractor set (Mahadevi Varma; Maulana Abul Kalam Azad; Abu’l-Fazl ibn Mubarak) 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 1949 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. Revision takeaway: remember the compact chain “Gunahon Ka Devta — Dharamvir Bharati — Hindi — 1949,” and connect it with Andha Yug 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. Similar periods, genres or national traditions do not make two book–author pairs interchangeable. Option A gives Dharamvir Bharati and satisfies the wording of the question. The remaining choices—Mahadevi Varma, Maulana Abul Kalam Azad and Abu’l-Fazl ibn Mubarak—do not satisfy the complete requirement.
