In the late 18th century, the presidencies of Bombay, Madras and Bengal developed from which of the following East India Company's trading posts?

The East India Company established its earliest trading posts at Surat (in western India, for Bombay Presidency), Madras (in southern India, for Madras Presidency), and Calcutta (in eastern India, for Bengal Presidency). These three trading centers evolved into the three presidencies of British India in the late 18th century. Bombay later replaced Surat as the headquarters of the western presidency.
