Answer: B

Explanation:

Until signature files can be updated, incoming e-mail containing picture file attachments should be blocked. Quarantining picture files already stored on file servers is not effective since these files must be intercepted before they are opened. Quarantine of all mail servers or blocking all incoming mail is unnecessary overkill since only those e-mails containing attached picture files are in question.
