Answer:
The correct answer is ''unfair discrimination''.
Step-by-step explanation:
On one hand, Channel Management is the name given, in the field of economics, to the term that refers to the strategy used by many companies to enter the world of consumers via marketing, with publicity specifically in order to reach the most amount of people possible. It is the way that the managers use the marketing techniques to get to the clientes with different channels, that could be for example tv, radio, cellphones, etc.
In the other hand, an unethical activity could be any type of action whose focus is on producing harm to people, therefore that an unfair discrimination is the answer because it is a possible action that could happen when using channel management due to the fact that many channels are used, and during the process a mistake could take place that produces that a person feels discriminated.
