@sammixboo Can you help me out please?

Well aviation was not developed until 1903, which is the 20th century. You can rule that off.

basically the first one was textile then come steam and after that steel so according to your option its steel

Textiles was Europe. Steel is the U.S as far as industrial revolution goes transportation is probably an effect of an industrial revolution but petroleum wouldn't surprise me either. If it's an essay you could make the case for steel.
