B) It is used for one-sample t-tests and does not assume that the central limit theorem is true.

The sampling distribution of the difference between means is used for two-sample t-tests and assumes that the central limit theorem is true. This distribution is used to test whether or not there is a significant difference between the means of two independent populations. Options A and D are incorrect, as they refer to one-sample t-tests, which do not involve a difference between means. Option B is incorrect, as the sampling distribution of the difference between means specifically applies to two-sample t-tests.
