The ______ of the email is a single line of text that the person sees when they get the email from anyone.

Correct option is B

Correct Answer: B) subject line
Explanation:
· The subject line is a brief summary of the email's content, appearing as a single line of text in the recipient's inbox alongside the sender's name.
· Its primary purpose is to give the recipient a quick idea of what the email is about before they decide to open it.
· A well-written subject line is crucial for clarity and determines whether an email is prioritized or ignored.
Information Booster:
· In modern email clients, if a subject line is left blank, the system often prompts the user with a warning before sending, as "no-subject" emails are more likely to be flagged as spam by filters.
· Most email providers also offer a "Snippet" or "Preview Text", which is the first few words of the email body shown right after the subject line to provide more context.
Additional Knowledge:
· Signature: This is a block of text automatically appended to the end of an outgoing email, typically containing the sender's name, contact details, or professional title.
· Meta data: This refers to the "data about data" hidden in the email header (like IP addresses, server paths, and timestamps) that tracks the email's journey but is not a single line of text intended for the recipient to read as a summary.
· Body: This is the main part of the email containing the actual message, images, or data. It is only visible in its entirety once the email has been opened.
