Answer:
If ORS wishes to tap Selden's expertise ,it would be preferable to have him serve as a consultant to the QRS board rather than joining the board as a member
Step-by-step explanation:
The conduct of professionals are guided by a set of rule called code of ethics so that they can be well guided in certain situation at any time in the point of duty.
The five fundamental principle of the code of conduct are objectivity , professional behavior , professional competence and due care , integrity and confidentiality.
In this scenario , the objectivity of of Selden is threatened if he joins the board and still continue to carry out the tax advisory service.
The situation is better managed if he serves as a consultant to the board members.
