Answer:b) Self-interested behavior
Explanation: Self-interested behavior is the behavior that is shown by the individual about keeping their own-self at advantage by focusing on their own self. This nature does not gives priority to other before the individual.
Jimmy is also showing the self interested behavior because he is allergic to the peanuts and thus declines the peanut bar from his friend by keeping himself at the focus. This act will protect Jimmy from catching the allergy.
Other option are incorrect because selfish behavior is showing self profiting nature and not considering others,and illogical nature is nature which does not makes sense.Thus the correct option is option(b).
