The correct answer is: A. Alivardi Khan
Alivardi Khan was the Nawab of Bengal from 1740 to 1756. He was a powerful and effective ruler who restored order to Bengal after a period of chaos. He was also a shrewd politician who was able to maintain good relations with the British East India Company. However, he was also suspicious of the Company’s growing power and in 1750 he ordered the closure of the Company’s factory at Patna.
Murshid Quli Khan was the Nawab of Bengal from 1717 to 1727. He was a capable administrator who oversaw a period of economic prosperity in Bengal. He was also a patron of the arts and literature. However, he was not as successful in dealing with the British East India Company as Alivardi Khan was. In 1726, he granted the Company the right to trade in Bengal, but he also imposed a number of restrictions on the Company’s activities.
Siraj-ud-daula was the Nawab of Bengal from 1756 to 1757. He was a young and inexperienced ruler who was not prepared to deal with the growing power of the British East India Company. In 1757, he attacked the Company’s fort at Calcutta, which led to the Battle of Plassey and the beginning of British rule in India.
The answer to the question is A. Alivardi Khan.
