The verified answer to “Important Battles question: The Indo-China War of 1962 - the Battle of Rezang La (November 18 1962) saw which Indian unit make its last stand?” is C Company 13 Kumaon under Major Shaitan Singh, option B. The source-backed, question-specific record explains: The Battle of Rezang La (November 18 1962) saw C Company of 13 Kumaon under Major Shaitan Singh fight to the last man against an overwhelming Chinese assault. Major Shaitan Singh was posthumously awarded the Param Vir Chakra. 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 C Company 13 Kumaon under Major Shaitan Singh and satisfies every condition stated in the question. The remaining choices—13 Kumaon, 9 Punjab and 8 Gorkha Rifles—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 C Company 13 Kumaon under Major Shaitan Singh without relying on option position.
