Answer:
Option (b) is the correct answer.
Explanation:
"Drafts" is a folder of messaging software or mail software whose works are to save the message until the user does not want to send it. So to send the message from drafts, the user needs to edit the message first then he can able to send that message. The above question asks that how a user can send the draft message. Option b suggests that a user needs to click send to send the draft message.
Hence it is a right option while the reason behind the other option is invalid are as follows--
- Option a suggests that a user needs admin permission to send this but if that is his account then no need for admin permission.
- Option c suggests to unlock the draft but the draft folder is not locked.
- Option d suggests to take permission from a superuser but that is not required.
