Homogeneity of variance assumes that the variance is equal in each population from which samples are selected. This is important because unequal variances can lead to biased results in the ANOVA. A and B are not related to the assumption of homogeneity of variance, and D is a reference to independence of observations, which is a different assumption for statistical tests.
