Potential penalties for disciplinary actions include all of the following except

NPPE materials explain that professional regulators have administrative authority to impose disciplinary sanctions such as reprimands, fines, licence suspension or cancellation, and remedial measures including education or mentorship.

Criminal penalties, including prison sentences, fall under the authority of the courts, not professional regulators. While regulators may cancel licences, they cannot impose criminal punishment.

Therefore, option D is the correct answer.
