The correct answer is B.
The Industrial Revolution was the process of transition from hand production methods to manufacturing production systems that ocurred in Europe and in the US at the end of the 18th century and during the 19th century. The whole process started in Great Britain that had important deposits of coal and iron (energy source and main industrial product) and, moreover most of the crucial technological innovations were originated in this country.
Also GB's position as leading trade nation, allowed to commercialize the new large industrial outputs and allowed the new sectors to become highly profitable and to continue renovating themselves.
