If large differences exist among the sample means, it indicates that there is a significant difference between at least two groups. This means that the null hypothesis, which states that all group means are equal, can be rejected in favor of the alternative hypothesis, which states that at least one group mean is different from the others. Therefore, the best choice is to reject the null hypothesis (choice A).
