Explanation:

Surendra Nath Sen, an eminent Indian historian, authored the scholarly work "Eighteen Fifty-Seven" (often referred to by titles like "1857 in India: Mutiny or War of Independence"), published in 1957. This book was commissioned by the Government of India to commemorate the centenary of the Revolt of 1857, providing a comprehensive and balanced account of the uprising. Maulana Azad wrote "India Wins Freedom." S.B. Chaudhari also wrote extensively on 1857 but S.N. Sen's work is the official centenary history. A.T. Embree was an American historian of South Asia.
