Final Answer :
C
Explanation :
The correlation coefficient that indicates the strongest relationship between two variables is the one closest to -1 or +1. Therefore, the strongest relationship is indicated by a correlation coefficient of -0.9. This means that the two variables are very strongly negatively correlated, so that as one variable increases, the other decreases predictably. This would enable us to make the most accurate predictions of one variable from the other.
