The assumptions of ANOVA are that the samples are selected randomly, the population distribution is normal, and the samples come from populations with equal variances. Option A is incorrect because ANOVA assumes that the populations have equal variances, not unequal variances. Option C is incorrect because it only includes the assumption of normality, but does not include the assumption of equal variances. Option D is incorrect because ANOVA assumes that the populations have equal variances, not heteroscedastic populations.
