Haphazard sampling is a non-probability sampling technique in which the researcher chooses the sample based on convenience or accessibility. In this scenario, the professor is choosing to survey students in the college cafeteria because they are easily accessible to him at that time. He is not selecting a random sample or attempting to ensure representation from different subgroups (stratification). Therefore, haphazard sampling is the most appropriate choice for this scenario.
