The Kruskal-Wallis test statistic can be approximated by a Chi-squared distribution with k - 1 degrees of freedom (where k is the number of populations) whenever the sample sizes are all greater than or equal to: $\begin{array}{|l|l|}
\hline \text { A. } & 30 \
\hline \text { B. } & 20 \
\hline \text { C. } & 10 \
\hline \text { D. } & 5 \
\hline
\end{array}$
