The source-backed, question-specific record explains: The Battle of Biderra, also written Bedara in some accounts, was fought near Chinsurah in Bengal in 1759. Company forces defeated a Dutch attempt to reinforce their position. The event is distinct from Plassey and provides a more useful additional battle fact than repeating Plassey’s location in two nearly identical questions. 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 Battle of Biderra and satisfies every condition stated in the question. The remaining choices—Battle of Wandiwash, Battle of Bedara in Java and Battle of Porto Novo—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 Battle of Biderra without relying on option position.
