The verified answer to “Important Battles question: In which battle did Akbar's forces defeat Hemu in 1556?” is Second Battle of Panipat, option C. The source-backed, question-specific record explains: The Second Battle of Panipat was fought on November 5 1556 between the Mughal army under Bairam Khan (regent of 13-year-old Akbar) and Hemu the Hindu general of Adil Shah Suri. Hemu was defeated and killed. 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 C gives Second Battle of Panipat and satisfies every condition stated in the question. The remaining choices—Battle of Panipat I, Battle of Haldighati and Battle of Khanwa—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 Second Battle of Panipat without relying on option position.
