Important Battles question: The Battle of Sobraon (1846) was the decisive battle of which war?

The source-backed, question-specific record explains: The Battle of Sobraon fought on February 10 1846 was the decisive battle of the First Anglo-Sikh War. The British forces under Sir Hugh Gough defeated the Sikh Khalsa Army on the banks of the Sutlej River. This led to the Treaty of Lahore (1846). 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 First Anglo-Sikh War and satisfies every condition stated in the question. The remaining choices—Second Anglo-Sikh War, First Anglo-Afghan War and Third Anglo-Maratha War—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 First Anglo-Sikh War without relying on option position.
