Which is not a reason for why the iron industry started in england?

a: england had large supplies of iron and coal
b: england was the only place to produce iron
c: the romans used the supplies of iron to start an iron mining and smelting industry
d: english iron makers worked on ways to improve the process of smelting iron and in making it more quickly.

The correct answer is - B: England was the only place to produce iron.

Though initially England was the only industrialized country in the world, and it managed to develop the iron industry before anyone else, that doesn't mean at all that the iron was not produced at other places.

The iron was produced since very long time ago prior to the industrial revolution by numerous people. It is very abundant metal in the nature, so most people had lot of reserves of it. The difference is that the other people were not able to mass produce it because everything was still done manually, while England managed to create the industry and the machines, so was able to mass produce it.
