Books and Authors question: In a comparison beginning with On the Origin of Species, which of the following book–author pairs is incorrectly matched?

The verified answer to “Books and Authors question: In a comparison beginning with On the Origin of Species, which of the following book–author pairs is incorrectly matched?” is On the Origin of Species — Adam Smith, option B. The source-backed, question-specific record explains: On the Origin of Species is correctly associated with Charles Darwin. These three details—title, author, and language—form the decisive bibliographical combination required here. The distractor set (The Wealth of Nations — Adam Smith; Capital, Volume I — Karl Marx; The Last Mughal — William Dalrymple) 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. Revision takeaway: remember the compact chain “On the Origin of Species — Charles Darwin — English — 1859,” and connect it with The Descent of Man 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 On the Origin of Species — Adam Smith and satisfies the wording of the question. The remaining choices—The Wealth of Nations — Adam Smith, Capital, Volume I — Karl Marx and The Last Mughal — William Dalrymple—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 by another author, reverse a correct association, or present a correct pair when the question specifically asks for the incorrect match.
