The verified answer to “Important Battles question: The Battle of Ghaghra (1529) was the last major battle fought by which Mughal emperor?” is Babur, option C. The source-backed, question-specific record explains: The Battle of Ghaghra fought in May 1529 was the last major battle of Babur's life. Babur died in December 1530. 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 Babur and satisfies every condition stated in the question. The remaining choices—Akbar, Humayun and Jahangir—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 Babur without relying on option position.
