Important Battles question: The Battle of Mahidpur (1817) was fought on the banks of which river?

The verified answer to “Important Battles question: The Battle of Mahidpur (1817) was fought on the banks of which river?” is Shipra, option B. The source-backed, question-specific record explains: The Battle of Mahidpur (December 21 1817) was fought on the banks of the Sipra (Shipra) River in Madhya Pradesh during the Third Anglo-Maratha War. 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 Shipra and satisfies every condition stated in the question. The remaining choices—Narmada, Mahi and Tapti—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 Shipra without relying on option position.
