The correct option is D Bahadur Shah II and General Bakht Khan
Bahadur Shah II and General Bakht Khan led the revolt in Delhi. Indian Rebellion of 1857 started when a group of sepoys rebelled against the introduction of rifle cartridges that were allegedly greased with lard (pig's fat). This offended the Muslim soldiers because they are not allowed to eat pig's meat in Islam. When Bakht Khan heard of the rebellion in Meerut, he decided to march to Delhi to support the Mughal emperor Bahadur Shah Zafar's army.
