The Spearman rank correlation coefficient must be used to determine whether a relationship exists between two variables when: $\begin{array}{|l|l|}\hline\text { A. } & \text { one of the variables may be ordinal.}\\\hline \text { B. } & \text { both of the variables may be ordinal.} \\\hline \text { C. } &\text { both variables are interval and the normality requirement may not be satisfied.}\\\hline \text { D. } &\text { All of these choices are correct.}\\\hline\end{array}$
