Answer: C. Everyone in their school.
Explanation: They surveyed every person at their school, so the population for this study is all people in that school. The student's error likely comes from confusing the terms "sample" and "population" — or assuming the population must be much larger (e.g., all people everywhere or all people with curly hair). Because they surveyed the entire school, this was a census of that population, not a sample.
