Marissa is using rationalization as a defense mechanism. Although "rationalization" is not listed as an option in your question, her statement reflects an attempt to justify her behavior (breaking the toy) by blaming the other person's actions (bothering her while she wants to play video games).
None of the provided options (compensation, denial, reaction formation, projection) accurately represent what she is doing. However, if you need to choose from those options, the closest might be projection, as she is attributing her feelings and frustrations onto the other person, though it's not a perfect fit.
