One-way within-subjects ANOVA assumes that the observations within each group are not independent, but the observations between groups are independent. Therefore, the correct assumption is that independent observations were made within groups but not between groups. A is incorrect because the population distribution does not affect the assumption for this test. B is incorrect because within-subjects ANOVA involves observing the same participants in each group, and the assumption is that the observations are not independent within each group.
