Answer 1

One advantage of communicating via email is that it is permanent (Option B). All the mails sent to a person remains intact. Even if the sender deletes the mail from his/her sentbox, the person who has received the mail as long as he/she does not delete it. Thus it is a permanent record of the interaction.

It cannot be considered temporary because of the same reason. It is not a secure or private conversation because the receiver or sender of the mail can forward it to anyone without the other's knowledge. It can be formal or informal.

Answer 2

One advantage of communication via email is that it is a secure and private communication.
An email takes place only between the sender and the receiver.
The information that is exchanged over the email is secure since only the sender and receiver are aware of it.
The information that is exchanged is saved on the server so that it can be referred to at any further date as well.
