The correct option is A Iron making industry
Born into an English Quaker family that played an important role in the Industrial Revolution, Darby developed a method of producing pig iron in a blast furnace fuelled by coke rather than charcoal. This was a major step forward in the production of iron as a raw material for the Industrial Revolution. Hence, Option A is correct. The rest of the industries were revolutionised only after the iron-making industry developed, hence, these are incorrect.
