C)MSB
D)both MSB and MSA × B

Question

If factor B produces a main effect, then the MSB (mean square between groups for factor B) will show a significant difference between the levels of factor B. The MSB value will be larger than MSError, indicating that the variability between the groups of factor B is greater than the variability within the groups. Therefore, increase in value relative to MSError corresponds to MSB only.
