The verified answer to “Books and Authors question: With Kamayani as the reference work, which book–author pair is correctly matched?” is Kamayani — Jaishankar Prasad, option B. The source-backed, question-specific record explains: Kamayani is correctly associated with Jaishankar Prasad. The work’s first publication is conventionally dated to 1936, and its original language is Hindi. These three details—title, author, and language—form the decisive bibliographical combination required here. Jaishankar Prasad, a major Indian literary figure, is also associated with Skandagupta; that companion title helps confirm the authorship independently rather than through guesswork. The distractor set (Gunahon Ka Devta — Bhagat Singh; Why I Am an Atheist — K. Nilakanta Sastri; A History of South India — Dharamvir Bharati) 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 “Kamayani — Jaishankar Prasad — Hindi — 1936,” and connect it with Skandagupta 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 B gives Kamayani — Jaishankar Prasad and satisfies the wording of the question. The remaining choices—Gunahon Ka Devta — Bhagat Singh, Why I Am an Atheist — K. Nilakanta Sastri and A History of South India — Dharamvir Bharati—do not satisfy the complete requirement.
