Competition factors
Answer:
If you can only choose one option then I would go with competition factors because that doesn't just apply to humans but to all other types of populations.
However, if you can choose several options and it talks about humans then I would go with all of them because it makes sense that financial factors affect the growth. Since if there isn't much money, not much growth can be made. Geographic factors also play a role because of the geographical location is bad it can make it hard for population growth to occur. Physical factors is also a possibilities because if the physical accessibility is limited then less growth will occur. Finally, competition factor will still take place therefore all options would work.
