Final answer:
The Maine Real Estate Commission can impose sanctions for ethical violations, fraud, and discrimination, but typically addresses failures in continuing education without disciplinary sanctions.
Step-by-step explanation:
The Maine Real Estate Commission is responsible for maintaining ethical standards within the real estate profession. Based on the options provided, the Commission may impose disciplinary sanctions in cases such as violating ethical standards and professional conduct, committing fraud or misrepresentation in real estate transactions, and engaging in discriminatory practices during real estate transactions. However, if a person fails to complete continuing education requirements, this is typically addressed through mandatory completion of education rather than disciplinary action unless the lack of continuing education is part of a broader pattern of professional misconduct.
