The correct answer is "at least one of the three population means is different from another mean". In population anova comparing studies the null hypothesis states that the mean of all of the studied treatment conditions are equal. The alternative hypothesis should be the contrary of which was is stated in the null hypothesis, which is at least one mean is different from the others.
