In the context of effect size for a one-way ANOVA, the term "d" typically refers to Cohen's d, which is a measure of effect size used more commonly in the context of t-tests rather than ANOVA.

Therefore, the statement that all of the other alternatives are correct is the best choice, even though the terminology might not perfectly align with the standard usage for ANOVA (where eta squared or partial eta squared are more commonly used to measure effect size).
