The correct answer is: a) Planning an armed rebellion.
Maniram Dewan and Piyali Barua were implicated in the 1857 Revolt due to their involvement in planning an armed rebellion against the British. They were both executed for their role in the rebellion.
The 1857 Revolt, also known as the Indian Rebellion of 1857 or the Sepoy Mutiny, was a major uprising against British rule in India. The revolt began on 10 May 1857 at the Meerut cantonment in Uttar Pradesh and spread rapidly across northern India. The rebels were motivated by a variety of factors, including religious and economic grievances, as well as a desire for independence from British rule.
The revolt was ultimately unsuccessful, but it had a profound impact on the history of India. It led to the end of the East India Company’s rule in India and the establishment of the British Raj. It also led to a number of reforms, including the introduction of Western education and the Indianization of the civil service.
Maniram Dewan was a prominent Assamese businessman and politician. He was a close associate of the Ahom king Purandar Singha and played a leading role in the modernization of Assam during the 19th century. He was also a strong advocate for Assamese self-rule and opposed British rule in Assam.
Piyali Barua was a prominent Assamese freedom fighter. He was a close associate of Maniram Dewan and played a leading role in the 1857 Revolt in Assam. He was executed by the British for his role in the rebellion.
The 1857 Revolt had a limited impact in Assam, but it did lead to the execution of Maniram Dewan and Piyali Barua. These two men were implicated in the rebellion due to their involvement in planning an armed rebellion against the British.
