The verified answer to “Books and Authors question: With Gunahon Ka Devta as the reference work, which book–author pair is correctly matched?” is Gunahon Ka Devta — Dharamvir Bharati, option C. 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 (Yama — Maulana Abul Kalam Azad; India Wins Freedom — Abu’l-Fazl ibn Mubarak; Akbarnama — Mahadevi Varma) must therefore be tested as complete statements: one true fragment cannot make an entire option correct. 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 “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 C gives Gunahon Ka Devta — Dharamvir Bharati and satisfies the wording of the question. The remaining choices—Yama — Maulana Abul Kalam Azad, India Wins Freedom — Abu’l-Fazl ibn Mubarak and Akbarnama — Mahadevi Varma—do not satisfy the complete requirement. Depending on the stem, a distractor may name a real writer but attach the wrong title, use a related work.
