In a 2 x 2 factorial design, there are two factors, each with two levels. Therefore, there are four possible conditions. Option C suggests that at least one of the factors has a significant main effect, but the other does not, and there is a significant interaction effect. This is a possible outcome for a 2 x 2 factorial design because it accounts for all three effects (two main effects and the interaction effect). All other options either include non-significant effects or more significant effects than possible in a 2 x2 factorial design.
