The denominator of the ratio for calculating the paired-samples t statistic is the estimated standard error of the distribution of mean difference scores, which represents the variability of the mean difference scores. This is because the t statistic is calculated by dividing the mean difference scores by their estimated standard error, making B the best choice for this question.
