Explanation

Maulavi Ahmadullah Shah of Faizabad was one of the prominent leaders of the Revolt of 1857 in Awadh. He was popularly known as 'Danka Shah' because he moved about with drums (danka) beating, proclaiming jihad and calling upon people to rise against the British. He led rebel forces around Lucknow and Faizabad and was regarded by the British as one of the ablest rebel leaders. He was killed at Powayan in June 1858. Shah Mal, Nana Sahib and Tantia Tope were associated with other centres and bore no such title. Hence option B is correct.
