Final answer:
Betty demonstrated assertive behavior by choosing to discuss an issue with her co-worker in person, which is a constructive and respectful way to communicate. The correct answer is option: Option 3: Assertive.
Step-by-step explanation:
Betty exhibited a assertive behavioral style in the situation described. By choosing to walk to her co-worker's office to discuss the email in person, Betty demonstrated that she was willing to engage in direct communication, likely with the goal of resolving the issue in a constructive and straightforward manner.
This approach is a hallmark of assertiveness, which is characterized by an individual's ability to express their thoughts, feelings, and needs in an open, honest, and respectful way.
Conversely, an aggressive behavior would have involved confrontational or domineering tactics, potentially alienating her co-worker. A passive approach would have been if Betty avoided the situation or failed to express her perspective.
Lastly, an avoidant behavior would have occurred if Betty ignored the email entirely or refused to acknowledge the issue.
