Marissa is using rationalization as her defense mechanism. She is justifying her behavior (breaking the toy) by blaming the other person for bothering her instead of acknowledging her own actions. However, it appears that "rationalization" is not listed in your options. Out of the options provided, none of them directly match.
If I have to choose, projection could somewhat fit as she is attributing her feelings of frustration towards the other person's behavior, but it still does not perfectly describe the situation. Projection typically involves attributing one’s own unacceptable thoughts or feelings to someone else.
If "rationalization" were an option, that would be the best fit. If not, based on your options, "projection" is the closest.
