A)eta-squared
B)omega-squared
C)estimated Cohen's d
D)both A and B

Both eta-squared and omega-squared are measures of proportion of variance for a one-way between-subjects ANOVA. While eta-squared is the traditional measure, omega-squared is a more appropriate choice for smaller sample sizes or if the assumption of homogeneity of variances is violated. Therefore, both options should be taken into account when analyzing the results of a one-way between-subjects ANOVA. Cohen's d, on the other hand, is a measure of effect size, but it does not provide information on the proportion of variance accounted for by the independent variable, so it is not a suitable choice for this question.
