The source-backed, question-specific record explains: After the French captured Madras, the Nawab of the Carnatic sent troops against them. A smaller disciplined French force defeated the Nawab’s much larger army near the Adyar River. The battle was not a French defeat of the British East India Company as the original stem claimed. 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 The Nawab of the Carnatic’s forces and satisfies every condition stated in the question. The remaining choices—The British garrison of Bombay, The Maratha Confederacy and The Mysore army of Tipu Sultan—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 The Nawab of the Carnatic’s forces without relying on option position.
