Correlated-groups t test requires a continuous dependent variable and a categorical independent variable with at least two levels. If the dependent variable has been measured on a nominal level, it cannot be analyzed using a t test, as it does not have an interval scale measurement. Therefore, option B is the correct choice. The other options (A, C, and D) are not conditions that make it inappropriate to use a correlated-groups t test.
