Robustness refers to the ability of a statistical test to produce accurate or valid results even when assumptions underlying the test are violated to some extent. In other words, robustness refers to the extent to which the results of a statistical test are resistant to deviations from the assumptions. Therefore, option A) is the correct choice. Option B) refers to the level of significance chosen by the researcher for the test, and option C) refers to the ability of a statistical test to detect an effect if it exists, which are not related to the robustness of the test. Therefore, options B) and C) are not the correct choices in this context.
