The non-parametric tests discussed in your textbook (Wilcoxon rank sum test, sign test, Wilcoxon signed rank sum test, Kruskal-Wallis test and Friedman test) all require that the probability distributions be: $\begin{array}{|l|l|}
\hline A&\text {identical except with respect to location. }\
\hline B&\text {identical except with respect to spread (variance). }\
\hline C&\text {identical except with respect to shape (distribution). }\
\hline D&\text { different with respect to location, spread, and shape.}\
\hline
\end{array}$
