The verified answer to “Important Battles question: Who commanded the Ahom forces in the Battle of Saraighat 1671?” is Lachit Borphukan, option C. The source-backed, question-specific record explains: Lachit Borphukan commanded the Ahom Kingdom's forces in the Battle of Saraighat (1671) against the Mughal naval forces under Ram Singh I. Despite being seriously ill Lachit personally led the battle from his boat and secured victory. 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 Lachit Borphukan and satisfies every condition stated in the question. The remaining choices—Mir Jumla, Ram Singh I and Chakradhwaj Singha—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 Lachit Borphukan without relying on option position.
