Question

Explanation:

A convenience sample uses easily accessible participants. Here, the student surveys attendees who voluntarily return bottles, which are readily available and self-selecting, fitting this sampling method. Stratified sampling divides the population into groups and samples from each, cluster sampling uses entire groups, and systematic sampling selects at fixed intervals—none match this scenario.
