The source-backed, question-specific record explains: Humayun defeated Mahmud Lodi and his Afghan supporters at Daurah in 1532. The original question incorrectly described the opponent as Sher Shah Suri’s brother Muhammad Shah Farmuli, conflating different people and political alignments. 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 A gives Mahmud Lodi and satisfies every condition stated in the question. The remaining choices—Sher Shah’s brother Muhammad Shah Farmuli, Islam Shah Suri and Adil Shah Suri—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 Mahmud Lodi without relying on option position.
