Answer
# Brief Explanations:
A good sampling method should be representative of the entire student - population. Option A asks parents instead of students. Option B only samples from one class, which may not be representative of all 500 students. Option D samples only students who bought vegetables at lunch, which is a biased sample. Option C randomly selects 100 students from the 500 - student population, providing a more representative sample.
# Answer:
C. Ask 100 randomly chosen students from the student population to choose their favorite vegetables.
