Why did the British exile Bahadur Shah Zafar to Burma?

He was a threat to British authority after the Indian Revolt of 1857

The correct answer is option 2- He was a threat to British authority after the Indian Revolt of 1857

Due to gradual decline of ardent patronage, highly skilled artists left the Mughal atelier and were welcomed by provincial Mughal rulers. These rulers imitated the Mughal royalties and wanted to recreate in paintings the glory of their dynasty and events of their court. Although some masterworks were produced during the periods of Muhammad Shah Rangila, Shah Alam II and Bhadur Shah Zafar, these were mere last flickers in the candle that was the Mughal miniature style. Bahadur Shah Zafar, painting, dated 1838, was made about two decades before he was exiled to Burma by the British, who were quick to see that no claimant to Mughal authority remains anywhere near Delhi to claim their imperial authority, after the failure of the Indian Revolt of 1857. He was the last Mughal ruler, who was also a poet, scholar and connoisseur. The new political environment, unsettled regional kingdoms and threat of English ascendancy changed the art scenario of India yet again. The painters thrived to suit the changing patrons, their aesthetic concerns, choice of subject matters and visual language. Eventually, the Mughal miniature style converged into other styles of the Provincial and Company School.
