Explanation:

After the suppression of the 1857 Revolt, Bahadur Shah Zafar, the last Mughal Emperor, was tried for treason by the British. He was subsequently exiled to Rangoon (now Yangon), which was then part of British Burma (now Myanmar), where he died in 1862. This marked the official end of the Mughal dynasty in India. Options A, B, and C (China, Iran, and Bhutan) are incorrect; these countries were not the destination for his exile.
