Arthur and Nicole are having an argument over the creation of a code of ethics for an organization. Arthur is of the view that it would be good for organizations to follow advice from the Institute of Business Ethics before creating a code of ethics, while Nicole disagrees with him. Which of the following advices would an organization follow if it agrees with Arthur?

a. The organization would develop its own model rather than picking a well-tested model.

b. The organization would put the code on the organization's website rather than sending it to all employees, suppliers, and others.

c. The organization would conduct an extensive survey involving every employee rather than getting endorsement from the board for the code of ethics.

d. The organization would determine the topics on which employees require guidance.
