The correct answer is internal.
Internal locus of control refers to when a person believes that he or she personally has control and responsibility for the outcomes in his or her life, and that external forces are not responsible for his or her life outcomes. For instance, a person with an internal locus of control is more likely to believe that his or her academic and job success (or lack thereof) lies in his or her control rather than in external factors such as others' intentions, unfairness, poor situations, etc.
