The source-backed, question-specific record explains: The First Battle of Panipat was fought on April 21, 1526, between Babur and Ibrahim Lodi, the Sultan of Delhi. 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 1526 and satisfies every condition stated in the question. The remaining choices—1556, 1761 and 1192—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 1526 without relying on option position.
