How can bcc (blind carbon copy) be used effectively?

A) When the writer wants the recipient to focus on content, not a lengthy list of other recipients
B) When asking the recipient to share information with unknown recipients
C) When sharing information with parties who might be interested in insider information
D) When you wish to be included in follow-up email exchanges
E) When you wish to put the recipient at a disadvantage with others

Answer: A
Explanation: A) When the list of names is long, and if you pasted all the email addresses into the email cc box, it would fill the screen. By using the bcc feature, you help ensure that your recipients focus on the message content rather than be distracted by an overly long header.
