The MS (within) is an estimate of the variance of individual measurements after accounting for the effects of the independent variable (i.e., treatment). MS (between) measures the variation between the sample means, and MS (total) measures the total variation in the data including both the variation between the sample means and the variation within the groups. Therefore, the best choice is B as it specifically estimates the within-group variability.
