Correct Answer: State Bank of India

Solution : The correct option is the State Bank of India .

The Bank of Calcutta, later renamed the Bank of Bengal, was established in 1806. It was one of the three presidential banks that were set up during British rule in India. The other two presidency banks were the Bank of Bombay (established in 1840) and the Bank of Madras (established in 1843). In 1921, these three presidential banks were merged to form the Imperial Bank of India, and later, in 1955, the Imperial Bank of India was nationalized and became the State Bank of India (SBI).
