The null hypothesis in an ANOVA test assumes that all means are equal. The alternative hypothesis is that at least one mean is different from the others. If the p-value is less than the significance level (usually 0.05), then we reject the null hypothesis and conclude that the means are not equal. In this case, the p-value is less than 0.05 (as indicated by the asterisk in the table), so we can conclude that the means are not equal. Therefore, the correct choice is C.
