A significant correlation between pairs of scores indicates a relationship between two variables, which can be explored through repeated-measures or matched-subjects designs that involve measuring the same individuals multiple times or matching individuals based on certain characteristics. Between-subjects design does not involve measuring the same individuals multiple times or matching them based on certain characteristics, which makes it less likely to yield a significant correlation between pairs of scores. Therefore, choice C is the best option because it includes both repeated-measures and matched-subjects designs.
