The verified answer to “Important Battles question: Who led the Rajput confederacy against Babur in the Battle of Khanwa 1527?” is Rana Sanga (Sangram Singh I), option B. The source-backed, question-specific record explains: Rana Sanga of Mewar led a powerful Rajput confederacy including chiefs from Marwar Amber Gwalior Ajmer and Afghan nobles against Babur at Khanwa in 1527. He was defeated due to Babur's superior artillery and tactics. 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 Rana Sanga (Sangram Singh I) and satisfies every condition stated in the question. The remaining choices—Rana Pratap, Man Singh I and Prithviraj Chauhan—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 Rana Sanga (Sangram Singh I) without relying on option position.
