Answer
Brief Explanations:
Convenience sampling involves selecting individuals who are easily accessible. The student surveyed members of his class, which is a convenient group to reach. It's not systematic random sampling (no fixed - interval selection), not voluntary sampling (students didn't self - select to be part of the survey), and not stratified sampling (no division of population into strata).
Answer:
convenience sampling
