Correct answer: D
Correct answer: MIME (Multipurpose Internet Mail Extensions) enables email to include multimedia content such as images, audio, video, and other file attachments.
Why MIME is used:
MIME defines content types (via the Content-Type header) and multipart structures so messages can carry different kinds of data in a single email.
It specifies encoding methods (for example, base64) to safely encode binary multimedia for transmission over protocols that expect text.
MIME works together with transport and access protocols (SMTP for sending, IMAP/POP3 for retrieving) to allow multimedia messages to be transmitted and accessed.
Contrast with other protocols:
SMTP handles sending messages but does not define how multimedia is formatted.
IMAP and POP3 handle access and retrieval of messages; they do not specify the encoding or content types for multimedia.
