The choice that best describes the push-pull nature of human migration is:
"While some people are pushed out of a place due to war or famine, other people are pulled towards a place because it offers more safety or economic opportunity."
This option accurately reflects the classic push-pull model of migration, where push factors (such as conflict or resource scarcity) drive people away from their homes, while pull factors (such as safety or better economic conditions) attract people to new locations.
