The power of a test is defined as the probability of correctly rejecting a null hypothesis that is false. Therefore, the best choice is rejecting a null hypothesis that is ESQ (correctly rejecting a false null hypothesis). Options A and B refer to incorrect decisions (rejecting or not rejecting a true null hypothesis), while option D refers to not rejecting a false null hypothesis (making a Type II error).
