The correct option is D BCC hides all of the recipient e-mail addresses, while CC does not
When you CC people on an e-mail the CC list is visible to all other recipients. For example, if you CC anu@example.com and bhanu@example.com on an e-mail, both Anu and Bhanu will get to know that e-mail is sent to other person also.
BCC stands for "blind carbon copy." Unlike with CC, no one can see the list of recipients on the BCC list.
