The dfError value represents the degrees of freedom for the error term in the ANOVA table, which is the variability that cannot be explained by the factors being tested. To calculate the dfError, we subtract the total degrees of freedom from the sum of the degrees of freedom for all the factors. In this case, the total degrees of freedom is not given, but we can estimate it to be 20 (since there are 21 observations in total). The sum of the degrees of freedom for all the factors is 2 + 2 + 4 = 8. Therefore, the dfError value is 20 - 8 = 12. The correct answer is C).
