All three choices are measures of the linear relationship between two variables. The covariance tells us the direction of the relationship and to what extent the two variables vary together. The coefficient of correlation provides a standardized measure of the strength and direction of the linear relationship between two variables. The coefficient of determination tells us the proportion of the variation in one variable that is predictable from the other variable. Therefore, all these choices are correct.
