Verified step by step guidance

1. Understand the context of the question: it asks about the population composition of Antarctica in terms of human inhabitants.
2. Recall that Antarctica is unique among continents because it has no permanent human residents or indigenous populations due to its extreme environment.
3. Recognize that the only people present on Antarctica are temporary residents, primarily scientists and support staff who live at research stations for limited periods.
4. Eliminate options that mention permanent residents, indigenous populations, or tourists staying most of the year, as these do not accurately describe the human presence on Antarctica.
5. Conclude that the majority of the population on Antarctica consists of scientists and support staff temporarily living at research stations.
