The Dunn procedure is used for post-hoc analysis following a statistically significant Kruskal-Wallis test, which is used to compare three or more independent groups on a non-parametric outcome variable. Therefore, choice B is the best option. The Wilcoxon signed-rank test, Mann-Whitney U test, and Wilcoxon rank sum test are also non-parametric tests, but they are used for different types of comparisons (e.g. paired samples, two independent samples). The Spearman rank-order correlation is a measure of association, not a test of significance for group differences.
