All options are correct statements about the coefficient of determination, also known as R-squared in bivariate regression. It varies between 0 and 1, signifies the proportion of the variation in the dependent variable (Y) explained by the independent variable (X), and is equal to the square of the correlation coefficient between the two variables. Therefore, the correct answer is D.
