I think the correct answer from the choices listed above is the second option. It is the OPEC that is a <span>political alliance that was created to protect the economic interests of Middle Eastern nations involved in oil production. Hope this answers the question. Have a nice day.</span><span />
From what I can see there are multiple correct answers. B and C are both correct. If you can only pick one I'd go with C. More recently businesses have moved more into cities.
