Statistical significance refers to the likelihood that an observed difference is not due to chance. However, practical significance relates to whether the observed difference is large enough to make a meaningful impact or inform social policies. If the observed difference is statistically significant but lacks practical significance, it means that the effect size is too small to be considered important in practice. Therefore, the best choice is D, practical significance.
