Trade and warfare. Trade can increase the countries wealth where war can destabilize a region leading to economic downturns.
All of the above are pull factors (reasons someone would want to leave their home country or area and move to another country or area)
I would choose option b: people are leaving rural areas and moving to urban areas; as the most likely reason because there are more job opportunities in urban (city) areas then rural (farmland) areas.
- war torn areas aren’t very common nowadays as reasons people would leave
- government policy is likely when moving from country to country but areas is also given in the question. Therefore it is not as likely of an answer
- land and resources is a valid answer for when areas were less urbanized; but also for when moving from country to country and less of area to area.
Hope this helped :)

One big difference between the two is that Saudi Arabia has very abundant oil reserves, which are the basis of its economy, and Yemen and Oman, despite being next to it, have very small oil reserves.
This also influences how rich the countries are, although in the recent years Oman is catching up on Saudi Arabia and it's not very poor.
