To create a valid MIME e-mail from the given plain-text message, the
correct answers are A,
C and D. A MIME e-mail must have the MIME-Version header at the start
of the e-mail, while
each segment (including the “root” segment) must sport both a Content-
Type and Content-
Transfer-Encoding header associated with it. The two other headers
mentioned in the answers
above are optional: Content-Disposition is used to indicate how the
segment should be
displayed (for instance, if it should be represented as an attachment)
and Content-ID is a
unique identifier optionally assigned to the content in the segment.
