The source-backed, question-specific record explains: After betraying Siraj ud-Daulah at the Battle of Plassey Mir Jafar was made the Nawab of Bengal by the British East India Company. 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 Made Nawab of Bengal and satisfies every condition stated in the question. The remaining choices—Given half of Bengal's revenue, Awarded a British title and Given the Zamindari of 24 Parganas—do not satisfy the complete requirement. Depending on the stem, a distractor may name a real commander but attach the wrong title, use a related event involving another power, reverse a correct association, or present a correct statement when the question specifically asks for the incorrect match. 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 Made Nawab of Bengal without relying on option position.
