The correct answer is 1 only. Explanation & Key Takeaways: The Battle of Plassey:- • When Alivardi Khan died in 1756, Siraj Ud-Daulah became the Nawab of Bengal. • The British were worried about power and keen on a puppet ruler who would willingly give trade concessions and other privileges. • Siraj Ud-Daulah asked the Company to stop meddling in the political affairs of his dominion, stop fortification, and pay the revenues. • After negotiations failed, the Nawab marched to the English factory at Kassimbazar and Calcutta to establish control over the Company’s fort. • British officials in Madras sent forces under the command of Robert Clive, reinforced by naval fleets. • In 1757, Robert Clive led the Company’s army against Siraj Ud-Daulah at Plassey. • One of the main reasons for the defeat of the Nawab was that the forces were led by Mir Jafar, one of Siraj Ud-Daulah's commanders. • Robert Clive had managed to secure the support of Mir Jafar by promising to make him nawab after crushing Siraj Ud-Daulah. • The Battle of Plassey became famous because it was the first major victory the British won in India. • After the defeat at Plassey, Siraj Ud-Daulah was assassinated and Mir Jafar made the nawab. • The Company was still unwilling to take over the responsibility of the administration. • Its prime objective was the expansion of trade. • When Mir Jafar protested, the Company deposed him and installed Mir Qasim in his place. • When Mir Qasim complained, he in turn was defeated in a battle fought at Buxar (1764), driven out of Bengal, and Mir Jafar was reinstalled.
