B. Developed an ideal self that guides her behavior.
C. Yet to encounter the psychological conflict of middle childhood.
D. Overcome the conflict of role confusion.

Eleven-year-old Leah is in Erikson's stage of development known as 'Industry vs. Inferiority', which typically occurs between the ages of 5 and 12. This stage is characterized by a focus on developing competence in various areas such as social, academic, and physical skills. Successful resolution of this stage's conflict results in a sense of mastery and proficiency, contributing to a positive self-concept. Leah demonstrates this by having a positive, realistic self-concept and taking pride in her accomplishments.

Key to this stage is the development of an ideal self, a concept of what one desires to be. Leah has developed this ideal self and uses it to guide her behavior, indicating that she has positively resolved the psychological conflict of middle childhood. However, as she enters adolescence, she will encounter a new conflict, that of 'Identity vs. Role Confusion'. This will involve forming a consistent sense of self and path for the future.
