In a two-way ANOVA, the model sum of squares (SSM) can be broken down into three terms: sum of squares for factor A (SSA), sum of squares for factor B (SSB), and sum of squares of the interaction of factor A and B (SSAB). Therefore, the best choice is C, which includes all three terms. Option A only includes error term while option B includes total sum of squares which is not required. Option D includes only two terms.
