Here's the reasoning for the correct order of events associated with the 'Revolt of 1857':

Sepoys in the cantonment of Meerut broke out in mutiny: The revolt began with the mutiny of sepoys in Meerut on May 10, 1857. This event marked the initial spark of the rebellion.

Bahadur Shah Zafar accepts nominal leadership: After the revolt in Meerut, Bahadur Shah Zafar, the last Mughal emperor, was declared as the nominal leader of the rebellion, which happened shortly after the Meerut mutiny.

Sepoys mutiny in Aligarh, Etawah, Mainpuri, and Etah: The mutiny among sepoys quickly spread to various other regions, including Aligarh, Etawah, Mainpuri, and Etah. These events followed the initial mutiny in Meerut and the recognition of Bahadur Shah Zafar as the leader.

Rising in Lucknow against the English: The uprising in Lucknow and the subsequent resistance against the British occurred as part of the wider revolt, following the earlier events in Meerut and other areas.

Azamgarh proclamation was made by mutineers: The Azamgarh proclamation was a later development in the revolt and took place after the events in Meerut, the recognition of Bahadur Shah Zafar, the spread of mutinies, and the resistance in Lucknow.

So, the correct order is (2) (B), (D), (E), (C), (A), as listed in option (2).
