Concept:Identify which leader from the 1857 revolt died in exile rather than in battle or by execution.
Explanation:After the 1857 revolt, Bahadur Shah Zafar was captured, tried for treason, and exiled to Rangoon, Burma (now Myanmar).
He spent his remaining years there and died in exile in 1862.
Rani Laxmibai fought in the battle of Gwalior and was killed in combat with British forces.
Tantia Tope was captured and hanged on 18 April 1859.
Nana Saheb also died in combat with British troops in the Nepal hills, not in exile.
Thus, only Bahadur Shah Zafar meets the condition of dying in exile.
Answer:B. Bahadur Shah Zafar
