The correct option is (b).
Explanation
The Revolt of 1857 involved a diverse range of leaders, including deposed rulers, religious figures, and local chieftains, who mobilized forces against British colonial rule across Northern and Central India.
Statement 1 is Incorrect:
Nana Saheb, the adopted son of the late Peshwa Baji Rao II, gathered armed forces and expelled the British garrison from Kanpur. He proclaimed himself Peshwa. However, he did not proclaim himself the Emperor of India; instead, he declared that he was a Governor under the Mughal Emperor Bahadur Shah Zafar, acknowledging the latter's suzerainty.
Statement 2 is Correct:
In the Mandla region of Madhya Pradesh, Rani Avantibai Lodhi of Ramgarh raised and led an army of four thousand against the British. She took this step after the British administration took over the governance of her state, removing her from power.
Statement 3 is Incorrect:
Ghazis or religious warriors did not support the British; rather, they came together to fight against the British. Many religious leaders and self-proclaimed warriors joined the rebellion, viewing the British rule as a threat to their religion and culture.
Key Takeaway:
Nana Saheb declared himself Peshwa under the authority of Emperor Bahadur Shah Zafar, while Rani Avantibai Lodhi was a key leader of the revolt in the Mandla region of Central India.
