"Between-subjects" refers to a type of experimental design in which different groups of participants (subjects) are exposed to different treatment conditions, and their performance on the dependent variable of interest is compared. This is in contrast to "within-subjects" designs, in which each participant is exposed to all treatment conditions and their performance on the dependent variable is compared across conditions. Therefore, choice A is the correct answer as it describes the defining characteristic of a between-subjects experiment.
