The verified answer to “Important Battles question: The Battle of Samugarh (1658) determined the Mughal succession. Who won?” is Aurangzeb, option B. The source-backed, question-specific record explains: The Battle of Samugarh (May 29 1658) fought near Agra was decisive in the Mughal War of Succession. Aurangzeb allied with Murad defeated the imperial forces under Dara Shikoh who fled. This effectively made Aurangzeb the Mughal Emperor. This evidence establishes the historical relationship required in this Important Battles item. A correct solution must preserve the exact battle, date, participants, commander, location, outcome or significance requested by the stem. Similar periods, genres or national traditions do not make two battle facts interchangeable. Option B gives Aurangzeb and satisfies every condition stated in the question. The remaining choices—Dara Shikoh, Shah Shuja and Murad—do not satisfy the complete requirement. The reliable checking method is to identify the named battle first, recall or verify its verified participant or outcome, and then read qualifiers such as “both works,” “original language,” “first published,” “correctly matched” or “incorrectly matched.” These qualifiers determine what counts as the answer. Replaying that method for this Important Battles question confirms Aurangzeb without relying on option position.
