A)n = 15 and SS = 10 for the difference scores
B)n = 15 and SS = 100 for the difference scores
C)n = 30 and SS = 10 for the difference scores
D)n = 30 and SS = 100 for the difference scores

The repeated-measures t statistic is more likely to be significant with a larger sample size (n) and a smaller sum of squares (SS) for the difference scores, as this suggests less variability and more reliability in the differences measured. Therefore, n = 30 and SS = 10 (option C) is the most likely to produce a significant value.
