r² is the coefficient of correlation, which measures the strength and direction of the linear relationship between two variables. The coefficient of determination, on the other hand, is the square of the coefficient of correlation and represents the percent of variation in Y that is explained by X. Therefore, statement B is correct and statement C is incorrect. Statement D is also incorrect because the coefficient of determination does not explain the variation in the error, but rather the variation in Y.
