Who among the following Mughal Emperors took part in the Revolt of 1857 ?

Bahadur Shah II

The correct answer is Option (3) → Bahadur Shah II

During the Revolt of 1857, Bahadur Shah II, also known as Bahadur Shah Zafar, played a symbolic role as the nominal leader of the rebellion. Bahadur Shah Zafar was the last Mughal emperor, and by the time of the uprising, the Mughal Empire had already lost its political power to the British East India Company. Despite being a figurehead with limited authority, he was chosen by the rebels as a symbol around whom they could rally. Bahadur Shah Zafar was declared the leader of the uprising, and he reluctantly assumed the role. The rebels sought to revive the Mughal authority and oppose the British rule. However, the British captured Delhi in September 1857, marking the end of the rebellion, and Bahadur Shah Zafar was subsequently captured, tried, and exiled by the British authorities. His participation in the events of 1857 was more symbolic than operational, reflecting the attempt by some elements of Indian society to resist British rule and revive a semblance of Mughal authority.

So, the correct option is [3].
