Important Battles question: What rights did the British gain after the Battle of Buxar through the Treaty of Allahabad 1765?

The verified answer to “Important Battles question: What rights did the British gain after the Battle of Buxar through the Treaty of Allahabad 1765?” is Diwani rights of Bengal Bihar and Orissa, option C. The source-backed, question-specific record explains: After the Battle of Buxar the Treaty of Allahabad (1765) was signed. Through this treaty Mughal Emperor Shah Alam II granted the Diwani (right to collect revenue) of Bengal Bihar and Orissa to 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 C gives Diwani rights of Bengal Bihar and Orissa and satisfies every condition stated in the question. The remaining choices—Trade monopoly, Military control of Delhi and Control of Punjab—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 Diwani rights of Bengal Bihar and Orissa without relying on option position. This approach builds accurate historical knowledge and careful option elimination for SSC, Railway, Banking, Defence, State and other competitive examinations.
