Answer: D. Everyone in their school.
Explanation: The students set out to study how many people in their school play an instrument, and they surveyed everyone in that school — so the population for that study is everyone in their school. The error likely comes from confusing "sample" with "population" or from assuming the population should be all instrument players everywhere. Surveying every member of the target population is a census (not a sample); calling it a sample would be incorrect unless the intended population was larger (e.g., all people who play an instrument).
