A random sample is the best choice as it ensures that each customer in the list has an equal chance of being selected for the sample, minimizing the potential for bias in the selection process. A systematic sample selects a sample based on a specific interval in the list, which could potentially overlook certain customers. A stratified sample divides the list into categories and selects a proportionate amount from each category, which may not be necessary or appropriate for this particular study. A comprehensive sample would entail selecting all 200 customers, which may not be feasible or necessary for the purposes of the study.
