Which of the Following Is the Most Effective Way to Deal

Which of the following is the most effective way to deal with online complaints?

A) There is so much online traffic that complaints tend to disappear into the background noise quickly, so the best thing to do is to ignore them.
B) Take responsibility for the problem quickly, apologizing if necessary, or treat it as an opportunity to demonstrate your company's responsiveness to problems.
C) Ethically speaking, web chats and posting boards should be entirely self-regulating, so companies should not intervene in any way even when there are complaints.
D) Because online complaints can spread quickly, it is important to take immediate legal action to have complaints removed from public view.
E) If the complaint is posted to a website or platform that you manage, delete the complaint immediately.
