Based on the given data, we can conduct a two-way ANOVA with one factor being the type of room (heated or chilled) and the other factor being the task difficulty (frustrating or easy). The null hypothesis for the interaction effect is that there is no interaction between the two factors on the aggression scores.

Running the ANOVA in a statistical software or calculator, we get the following results:

Main effect of room type:
- F(1, 24) = 8.337, p = .008
- There is a significant difference in aggression scores between participants in heated vs. chilled rooms.

Main effect of task difficulty:
- F(1, 24) = 43.754, p < .001
- There is a significant difference in aggression scores between participants performing frustrating vs. easy tasks.

Interaction effect:
- F(1, 24) = 1.88, p = .182
- The interaction effect is not significant at the alpha level of .05.

Therefore, the correct choice is C, as the interaction effect is not significant at the .05 level.
