What is Sepoy Rebellion of 1857?
Widespread but ineffectual resistance against British rule in India between 1857 and 1859 is known as the Indian Mutiny, also known as the Sepoy Mutiny or the First War of Independence. Indian soldiers working for the British East India Company started it at Meerut, and it afterwards spread to Delhi, Agra, Kanpur, and Lucknow.
The development of new rifle cartridges, which were said to be greased with grease made of cow and pig fat, was the primary contributor to the Sepoy Mutiny. Both Hindu and Muslim soldiers were offended by the requirement that the new cartridge be chewed before being inserted into the rifle.
Thus, option B is correct.
