Correct option is B
The Indian High Courts Act of 1861 was passed by the British Parliament to establish High Courts of Judicature in India. This Act authorized the Crown to establish High Courts at Calcutta, Bombay, and Madras by merging the Supreme Courts and the Sadar Adalats (civil and criminal courts) into unified High Courts. The Act provided for a Chief Justice and a maximum of 15 judges for each High Court. The first High Court to be established under this Act was the Calcutta High Court in 1862, followed by Bombay and Madras. Thus, the correct answer is 1861, when the Act was passed to legally create these High Courts.
