In a two-way ANOVA where both independent variables are between factors, the sum of squares total is partitioned into four parts: sum of squares between variable A, sum of squares between variable B, sum of squares interaction, and sum of squares error. Only three of them (sum of squares between variable A, sum of squares between variable B, and sum of squares interaction) are part of the explained variance. Therefore, the best choice is C.
