The verified answer to “Important Battles question: The Battle of Kanauj (1540) resulted in which outcome?” is Sher Shah Suri defeated Humayun, option B. The source-backed, question-specific record explains: In the Battle of Kanauj (also known as Battle of Bilgram) fought on May 17, 1540, Sher Shah Suri decisively defeated Humayun, forcing him into exile for 15 years. Sher Shah established the Sur Empire. 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 Sher Shah Suri defeated Humayun and satisfies every condition stated in the question. The remaining choices—Humayun defeated Sher Shah, Akbar defeated Hemu and Bahlul Lodi defeated Rana Sanga—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 Sher Shah Suri defeated Humayun without relying on option position.
