Important Battles question: What changed between the First and Second Battles of Tarain?

The source-backed, question-specific record explains: Prithviraj III defeated Muhammad of Ghor in the first encounter in 1191. Muhammad returned the next year with a reorganised campaign and won the second battle, opening the way for Ghurid expansion. Precise army totals such as 120,000 come from uncertain narrative traditions and should not be treated as secure statistics. This evidence establishes the historical relationship required in this Important Battles item. Option A gives Prithviraj won in 1191, but Muhammad of Ghor returned and won in 1192 and satisfies every condition stated in the question. The remaining choices—The same side won both without opposition, The battles occurred a century apart and Both ended in permanent peace—do not satisfy the complete requirement. Depending on the stem, a distractor may name a real commander but attach the wrong title, use a related event involving another power, reverse a correct association, or present a correct statement when the question specifically asks for the incorrect match. 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 Prithviraj won in 1191, but Muhammad of Ghor returned and won in 1192 without relying on option position.
