Important Battles question: The Battle of Saragarhi's 21 Sikh soldiers belonged to which battalion?

The verified answer to “Important Battles question: The Battle of Saragarhi's 21 Sikh soldiers belonged to which battalion?” is 4th Battalion Sikh Regiment (36th Sikh Infantry), option B. The source-backed, question-specific record explains: The 21 soldiers who died at the Battle of Saragarhi (1897) belonged to the 36th Sikh Infantry (later reorganized as the 4th Battalion of the Sikh Regiment). 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 4th Battalion Sikh Regiment (36th Sikh Infantry) and satisfies every condition stated in the question. The remaining choices—1st Sikh Infantry, 10th Sikh Infantry and Guides Infantry—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 4th Battalion Sikh Regiment (36th Sikh Infantry) without relying on option position.
