A) one or both variables may be ordinal
B) both variables are interval but the normality requirement is not met
C) both one or both variables may be ordinal and both variables are interval but the normality requirement is not met
D) neither one or both variables may be ordinal nor both variables are interval but the normality requirement is not met
E) none of these

The Spearman rank correlation coefficient is used when one or both variables are ordinal or when both variables are interval but do not meet the normality requirement. This makes it a non-parametric measure of correlation, suitable for cases where the Pearson correlation coefficient's assumptions are not met.
