B)The simple effects of factor B are not equal to the main effect of factor B.

If Fobs for the interaction in a two-factor between-subjects analysis of variance is statistically significant, it means that there is a significant difference between the simple effects of factors A and B at different levels. However, there is no evidence to suggest that the simple effects of factors A and B are different from their main effects. Therefore, option D is not true.
