Which of the Following Best Explains Why E-Mail Is a Poor

Which of the following best explains why e-mail is a poor choice for communicating sensitive messages?

A) E-mail is too fast for accommodating emotional messages. Once a message is sent, there is no "taking back" what has been said.
B) Nonverbal communication is not possible with e-mail. So, for example, it is difficult to reassure a person that things will be "all right" in the wake of bad news.
C) E-mail is too slow for accommodating emotional messages. Once a message is sent you might need to wait a long time for a response, and by that time your feelings have changed.
D) E-mail is too permanent for accommodating emotional messages. People don't want to have a written record of what they said when it includes emotional content.
