The people who have fled their homes but remain within national borders are called '________'.

Internally displaced people

The correct answer is Option (4) → Internally displaced people

" Poverty in the South has also led to large-scale migration to seek a better life, especially better economic opportunities, in the North. This has created international political frictions. International law and norms make a distinction between migrants (those who voluntarily leave their home countries) and refugees (those who flee from war, natural disaster or political persecution). States are generally supposed to accept refugees, but they do not have to accept migrants. While refugees leave their country of origin, people who have fled their homes but remain within national borders are called ‘internally displaced people’. Kashmiri Pandits that fled the violence in the Kashmir Valley in the early 1990s are an example of an internally displaced community.".
