The lower the probability value, the more significant the result is in statistical terms. A probability value of .01 (or 1%) is considered highly significant and is commonly used as a cutoff for rejecting a null hypothesis in statistical testing. This level of significance indicates that it is very unlikely that the result occurred by chance. Therefore, choice D with a probability value of .01 is the most highly significant in statistical terms.
