Final answer:
A REALTOR ethics hearing panel may recommend providing additional training and support or publicly reprimanding the member as a disciplinary action, but not a commendation or promotion.
Step-by-step explanation:
The student has asked about the potential disciplinary action that Ava, as a member of a REALTOR ethics hearing panel, can recommend for another member of the board after deliberations. Among the options provided, offering a promotion is not a disciplinary action. The appropriate disciplinary measures that could be recommended are providing additional training and support and publicly reprimanding the member. A commendation for ethical conduct is not a penalty but rather a recognition of good practice, so it is not suitable in a situation requiring disciplinary action.
