The prophecy that the end of British rule would lead to the end of the Kali Yuga and the return of Ram Rajya was NOT a known cause of the Revolt of 1857.
The Revolt of 1857 had multiple causes, including political grievances, economic exploitation, social and religious factors, and military issues. Rumours, prophecies, and popular discontent played a significant role in igniting and spreading the rebellion.
Options A, B, and C are all widely recognized causes or contributing factors to the Revolt of 1857. The rumour about greased cartridges and contaminated flour (A) was a major immediate trigger, playing on religious fears. The belief tied to the centenary of the Battle of Plassey (B) reflects the anti-British sentiment and anticipation of the end of their rule. Popular discontent (C) was a pervasive underlying cause stemming from decades of British policies. While the revolt had religious dimensions and rebels often fought for the restoration of traditional rule (like the Mughal Emperor or Maratha Peshwa), the specific prophecy regarding Kali Yuga and Ram Rajya (D) is not typically listed among the established major causes or motivating factors of the revolt in historical accounts.
