Random selection refers to the process of choosing participants from a population, while random assignment refers to the process of randomly assigning the selected participants to different groups (e.g., experimental and control). Therefore, option C correctly distinguishes between these two concepts. Option A is incorrect because random assignment is not used to obtain a sample, but rather to assign participants to different groups. Option B is incorrect because it confuses random selection and random assignment. Option D is incorrect because random assignment does not concern how we initially choose participants, but rather how we assign them to the groups.
