C. A 3x2 between-subjects, factorial design
Explanation:
Here a factorial design needs to be considered. Factorial design is used when there is more than one independent variable or factor which has more than one level. Here, noise is independent factor with three levels which are high, medium, and low and caffeine has two levels which are no caffeine or a high level of caffeine. Also, participants have received either no caffeine or a high level of caffeine. This means that it is a between-subjects or between-groups study with one group having no caffeine and other having high caffeine. Hence, 3x2 between-subjects factorial design is the most appropriate here.
