The verified answer to “Books and Authors question: With Yama as the reference work, which book–author pair is correctly matched?” is Yama — Mahadevi Varma, option D. The source-backed, question-specific record explains: Yama is correctly associated with Mahadevi Varma. The work’s first publication is conventionally dated to 1940, and its original language is Hindi. These three details—title, author, and language—form the decisive bibliographical combination required here. Mahadevi Varma, a major Indian literary figure, is also associated with Shrinkhala Ki Kariyan; that companion title helps confirm the authorship independently rather than through guesswork. The distractor set (Why I Am an Atheist — Romila Thapar; Early India: From the Origins to AD 1300 — Munshi Premchand; Godan — Bhagat Singh) 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 “Yama — Mahadevi Varma — Hindi — 1940,” and connect it with Shrinkhala Ki Kariyan 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 D gives Yama — Mahadevi Varma and satisfies the wording of the question. The remaining choices—Why I Am an Atheist — Romila Thapar, Early India: From the Origins to AD 1300 — Munshi Premchand and Godan — Bhagat Singh—do not satisfy the complete requirement.
