The verified answer to “Important Battles question: The Battle of Udgir (1760) was fought between which two powers?” is Marathas and Nizam of Hyderabad, option B. The source-backed, question-specific record explains: The Battle of Udgir (January 3 1760) was fought between the Maratha Confederacy under Vishwasrao and Bhau Sahib and the Nizam of Hyderabad. The Marathas won decisively and the Nizam had to cede large territories to the Marathas. 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 B gives Marathas and Nizam of Hyderabad and satisfies every condition stated in the question. The remaining choices—British and Marathas, Mughal and Marathas and Hyder Ali and Marathas—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 Marathas and Nizam of Hyderabad 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.
