The Wilcoxon signed-ranks T test is used as a nonparametric alternative to the related samples t-test, which compares the means of two related groups. Therefore, the best choice is C, related samples t-test. Option A, one-sample t-test, compares the sample mean to a known or hypothesized population mean, and option B, two-independent sample t-test, compares the means of two independent groups. Option D is incorrect because it includes option A, which is not parametrically related to the Wilcoxon signed-ranks T test.
