Which of the following is a sign of not taking personal responsibility?

Believing that apologizing is a sign of weakness signifies a lack of personal responsibility because it reflects an unwillingness to acknowledge one's faults or mistakes. Taking personal responsibility involves recognizing when one's actions have impacted others and being willing to admit those shortcomings, which includes offering an apology when appropriate. When someone perceives an apology as a weakness, they are more likely to avoid accountability for their actions or the consequences that arise from them. This mindset can hinder personal growth and the development of strong relationships, as it creates barriers to effective communication and accountability.

In contrast, admitting mistakes, seeking help when needed, and accepting feedback from others are all indicators of a responsible individual who takes ownership of their actions and is open to improving themselves and learning from their experiences.
