A repeated-measures design involves measuring the same participants in different conditions, which is what is happening in this study where participants are being measured in response time for both a familiar and unfamiliar word. A matched-samples design involves pairing participants based on some characteristic and then randomly assigning one member of each pair to an experimental group, which is not what is happening in this study. Therefore, the best choice is A for a repeated-measures design.
