Answer 1

Hint:
An extremely significant event in Indian history is the Rebellion of 1857, also known as India's First War of Independence. Sepoy Mangal Pandey started the revolt of 1857. The leaders of the revolt were Shahzada Firoz Shah and Kunwar Singh.

Complete answer:
The 1857 revolt was a prolonged time of armed insurrection and rebellion against British control of that portion of the subcontinent in Northern and Central India.
In 1857-58, the sepoy mutiny was a generalized but unsuccessful revolt against British rule in India. A rumor circulated amongst the sepoys that a mixture of pigs' and cows' lard was the grease used to lubricate the cartridges. This had injured the religious feelings of both Hindus and Muslims, which was one of the immediate causes of the sepoy mutiny of 1857.
Some more reasons of Revolt

Social and Religious causes - The British reversed their policy of non-interference in Indians' socio-religious lives. By the 1850 Religious Disabilities Act, the traditional Hindu legislation was changed. The change of faith, according to him does not preclude a son from inheriting the property of his heathen father.
Economic causes: British rule contributed to the failure of the self-sufficiency of the village, the commercialization of agriculture that burdened the peasantry, the embrace of imperialism for free trade from 1800, the de-industrialization, and the drain of capital, all of which led to the economy's overall decline.
Political Causes: The last major expansion of the British Indian territories took place during Dalhousie's tenure. Dalhousie announced in 1849 that the heir to Bahadur Shah II would have to abandon the Red Castle. Nevertheless, the annexation of Baghat and Udaipur was canceled and they were returned to their governing houses. He was overruled by the court of Directors when Dalhousie decided to apply the Doctrine of Lapse to Karauli (Rajputana).


Therefore the answer is B

Note:
This war brought about the end of the British East India Company’s rule in India, and led to the direct rule by the British Government of much of the Indian Subcontinent for the next 90 years. It was commonly called the National Revolt.
