Assertion: Calcutta, Bombay and Madras supplied raw materials for industry in England, and had emerged because of modern economic forces like capitalism.
Reasoning: Their economies were primarily based on factory production i.e. secondary sector.

The Assertion is correct but the Reason is incorrect.

Although Calcutta, Bombay and Madras supplied raw materials for industry in England, and had emerged because of modern economic forces like capitalism, their economies were not primarily based on factory production. The majority of the working population in these cities belonged to what economists classify as the tertiary sector.
