One way to ensure that the expected frequencies are no lower than approximately 5 is to increase the sample size. This will help to ensure that the data is distributed evenly across categories, and that there are enough data points within each category to achieve reliable results. Adding a third group or conducting a goodness-of-fit test may not be necessary, depending on the specific research question and data being analyzed. The choice D is not relevant to this question as eta-squared is a measure of effect size, not a method for meeting assumptions of a statistical test.
