Answer
# Brief Explanations:
In simple random sampling, every member of the population has an equal chance of being selected. Here, the principal generates random identification numbers and students with those numbers are selected for the survey. Each student's ID has an equal probability of being chosen, which is characteristic of simple - random sampling. Stratified sampling divides the population into subgroups and samples from each subgroup. Quota sampling sets quotas for different subgroups. Convenience sampling selects samples based on ease of access.
# Answer:
simple random sampling
