Prompt
What is the Bcc address field for?

Blind carbon copy

Explanation:

The Bcc (Blind carbon copy) field in simple words, is a field in which addresses inserted there are not all allowed to see other recipients of the message they receive. In other words, each recipient is blind to such information.

For example, if a teacher emails an assignment to a selection of 30 students from her class by inserting their email addresses in the Bcc field, it therefore means that each student would receive the email but would be unable to see other email addresses that receive the same email. However, they would be able to do so if they were inserted in the Cc field by the teacher.

i think the answer is b.
