The verified answer to “Important Battles question: The Battle of Delhi (1803) during the Second Anglo-Maratha War resulted in which Mughal emperor coming under British protection?” is Shah Alam II, option C. The source-backed, question-specific record explains: The Battle of Delhi (September 11 1803) saw General Lord Lake's British forces defeat the Maratha troops protecting Delhi. The blind Mughal Emperor Shah Alam II subsequently came under British protection effectively ending Maratha control of Delhi. 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 C gives Shah Alam II and satisfies every condition stated in the question. The remaining choices—Bahadur Shah II, Akbar II and Muhammad Shah—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 Shah Alam II without relying on option position.
