Based on the statement provided, Marissa is using the defense mechanism of justification, which is not listed as one of the options. However, if we were to choose the closest defense mechanism among the given options, it would be "denial."

The defense mechanism that Marissa is using when she says, "So what if I broke her stupid toy? She’s always bothering me when I want to play video games and no one should have to put up with that all the time," is c. reaction formation.

Explanation:
To identify the defense mechanism being used by Marissa, let's understand the definition of each option:

a. Compensation: This involves trying to make up for a perceived weakness or limitation by emphasizing strengths in other areas. For example, if someone believes they are not attractive, they may become an overachiever in academics or athletics to compensate.

b. Denial: Denial is the refusal to accept or acknowledge an uncomfortable truth or reality. For example, someone might deny having a drinking problem despite clear evidence that they do.

c. Reaction formation: This defense mechanism involves expressing the opposite feeling or belief to what is being experienced inwardly. For example, if someone unconsciously feels anger towards a person, they may outwardly display excessive friendliness towards them.

d. Projection: Projection involves attributing one's own unwanted thoughts or feelings onto someone else. For example, if someone has feelings of jealousy, they may accuse others of being jealous of them.

In the given statement, Marissa is expressing hostile and defensive thoughts about her sister's behavior. However, instead of acknowledging her own frustration or annoyance directly, she reacts by minimizing her actions and presenting herself as the victim. This contrasts with her true feelings, which may involve guilt or a recognition of her responsibility for breaking the toy. This discrepancy between her true feelings and her outward reaction is an example of reaction formation.
