Important Battles question: Who won the Battle of Chausa (1539)?

The verified answer to “Important Battles question: Who won the Battle of Chausa (1539)?” is Sher Shah Suri, option B. The source-backed, question-specific record explains: Sher Shah Suri won the Battle of Chausa in 1539, defeating Humayun. This was the first major defeat of Humayun by Sher Shah, who then went on to win the Battle of Kanauj in 1540, forcing Humayun into exile. 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 and satisfies every condition stated in the question. The remaining choices—Humayun, Akbar and Bahadur Shah—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 without relying on option position.
