When "p < .05," it indicates that the probability of the observed data (or something more extreme) occurring under the null hypothesis is less than 5%, suggesting that the results are statistically significant. This typically leads to the rejection of the null hypothesis (A) and supports the claim that the difference analyzed (e.g., by a t-test) is statistically significant (B). Therefore, both descriptive alternatives are correct.
