When a statistical test produces a very low p-value such as .01, it means that there is a low probability of obtaining the observed results under the assumption of the null hypothesis. Therefore, it is probably safe to reject the null hypothesis (A). Additionally, the low p-value provides support for the alternative hypothesis, which could be either one-tailed or two-tailed, depending on the research question (B). Finally, the low p-value indicates a lack of support for the null research hypothesis (C). All of these statements are true, therefore the correct answer is D.
