What is the purpose of header information in an email?

• A. To format the body of the email
• B. To show the sender, recipient, and subject of the email
• C. To manage email attachments
• D. To track the email delivery status

Answer: (B)

Header information in an email carries metadata that identifies who sent the message, who it's for, and what it's about. This lets mail servers route the message from the sender to the recipient and lets your email client display key details like the sender, the recipients, and the subject in your inbox. The body holds the actual message content and its formatting, while attachments are included as part of the message body using MIME parts, not in the header. Delivery-status details may exist in some headers, but the primary role of the header is to provide this identifying information and topic so the message reaches the right place and is easy to understand at a glance.
