The coefficient of multiple determination (R-squared) indicates the proportion of variation in the dependent variable that is explained by the independent variables. Therefore, if the R-squared is 0.81, it means that 81% of the variation in the dependent variable is explained by the independent variables. The remaining 19% of the variation is unexplained and could be due to other factors not included in the model, measurement error, or random chance. Thus, the answer is A) 19%.
