A)that the dependent variable be measured on an interval or ratio scale.

The t-test for related samples requires that each score in one sample be paired with a particular score in the other sample. The other assumptions for both the t-test for related and independent samples include that the dependent variable be measured on an interval or ratio scale, and that the population represented by either sample form a normal distribution. Homogeneity of variance is an assumption specific to the t-test for independent samples.
