Sorting a collection of cases into two or more groups is referred to as random assignment, whereas selecting a smaller subset of cases from a larger pool of cases is referred to as random sampling. Purposive sampling refers to selecting cases based on a specific purpose or criteria, whereas selective sampling refers to choosing cases that are not representative of the population. Therefore, the best choice is D, as it correctly matches the two terms and distinguishes them from other sampling methods.
