To find the critical value for a Kruskal-Wallis test with a 0.05 significance level and five populations, we need to use a chi-square distribution with degrees of freedom (df) equal to the number of populations minus one, which is 5-1=4. Using a chi-square distribution table or calculator, we can find the critical value to be 9.488. Therefore, the answer is C.
