The verified answer to “Important Battles question: The Battle of Chandawar (1194) was fought between Muhammad of Ghor and whom?” is Jaichand (Jayachandra) of Kannauj, option B. The source-backed, question-specific record explains: The Battle of Chandawar was fought in 1194 between Muhammad of Ghor (through his general Qutb ud-Din Aibak) and Jaichand (Jayachandra) of the Gahadavala dynasty of Kannauj. Jaichand was defeated and killed. 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 Jaichand (Jayachandra) of Kannauj and satisfies every condition stated in the question. The remaining choices—Prithviraj Chauhan, Bhimdev II of Gujarat and Paramardi of Chandela—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 Jaichand (Jayachandra) of Kannauj 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.
