In psychological research, a sample is a subset of the larger population that is being studied. In this scenario, the cars that are stopped at the checkpoint are a random sample of all the cars that pass by. Therefore, the best choice is A, sample. B (subset) could also be a valid option, but it is not the most precise term for this specific situation. C (cohort) and D (population) are not accurate choices as they refer to specific groups of people, rather than a subset of all cars passing through a DUI checkpoint.
