The correct option is B 1856
The General Service Enlistment Act passed in the year 1856 contained the provision that mandated soldiers or recruits of the Bengal Army to serve within or outside India when ordered. It meant that they were to sent overseas and sea voyages to serve. The Bengal Army mainly consisted of High Castes Hindus like Brahmins who according to their faith believed that they could lose their caste, religion, and faith if they cross the seas. This leads the sepoys to think that the Company was trying to defame their religion.
