The correct answer is: British East India Company.
The Battle of Buxar was fought on 22 October 1764 between the British East India Company and the Nawab of Bengal, Siraj ud-Daulah, along with his allies, the Mughal emperor Shah Alam II and the Nawab of Awadh, Shuja-ud-Daula. The British were victorious, and as a result, the Diwani (revenue collection) rights of Bengal, Bihar, and Orissa were granted to the British East India Company by the Mughal emperor. This gave the British Company control over the vast majority of the Mughal Empire’s revenue, and it was a major turning point in the history of British India.
The Maratha Confederacy was a Hindu confederacy that ruled over much of India in the 18th and 19th centuries. The Confederacy was founded in 1674 by Shivaji Maharaj, and it reached its peak under the leadership of Bajirao I in the early 18th century. The Maratha Confederacy was a powerful military force, and it played a major role in the decline of the Mughal Empire. However, the Confederacy was eventually defeated by the British East India Company in the early 19th century.
The Nawab of Bengal was the ruler of the Bengal Subah, one of the largest and most prosperous provinces of the Mughal Empire. The Nawab was appointed by the Mughal emperor, and he held a great deal of power and authority. However, the Nawab’s power was gradually eroded by the British East India Company, and in 1757, the British defeated the Nawab’s army at the Battle of Plassey. This victory gave the British control over Bengal, and it marked the beginning of the British Raj in India.
The French East India Company was a French trading company that was founded in 1664. The Company was granted a monopoly on trade with India by the French government, and it established a number of trading posts in India. However, the Company was never as successful as the British East India Company, and it was eventually dissolved in 1794.
