Answer:
The correct answer is letter "C": payment plans.
Step-by-step explanation:
Highly ethical organizations are those with a well-established Code of Ethics that comprises its corporate credos and values. Within a company, the idea of having "heroes" also helps to spread good practices since they are taken as role models so other employees tend to follow their example. Managers must be aware of the ethical behavior of employees to correct or eliminate any existing threat.
Thus, having different payment plans are not considered in the setting of a corporation's Code of Ethics.
