Which one among the following prominently rose in revolt against the British in 1857?

The Indian Rebellion of 1857 was primarily driven by the mutiny of the Bengal Army [4]. While the revolt began in Meerut, it was the sepoys of the Bengal Presidency who rose in prominent revolt due to grievances over the Enfield rifle's greased cartridges and the annexation of Awadh [4]. The Bengal Army was largely recruited from the high-caste populations of Awadh and eastern Uttar Pradesh, leading to Awadh being termed the 'nursery of the Bengal Army' [1]. In contrast, the Madras and Bombay Armies remained relatively unaffected and largely loyal to the British [2]. Although units from Awadh rebelled en masse, they were technically part of the irregular or regular structures of the Bengal Army's recruitment base [1]. The rebellion's core military strength and initial spark were almost exclusively centered within the Bengal Army's native infantry and cavalry regiments [2].
