A.
Asking 100 randomly chosen students is a simple random sample of a substantial fraction of the 500 students, which minimizes bias and gives a representative estimate.
B is biased (only those who already buy vegetables). C asks parents, not the students themselves. D is a small cluster that may not be representative of the whole school.
