What does the symbol '>>' indicate when replying to an email?

The symbol '>>' when replying to an email typically indicates that the text following it is quoted from the previous email. This convention is used to show continuity in conversation, allowing the recipient to see the context of the current message within the thread. By including this notation, it becomes easier for everyone involved to understand the discussion without having to scroll back through previous messages. This practice helps maintain clear communication, especially in threaded discussions where multiple replies and forwards can make it difficult to track the original messages.

The other options represent different functions or indications that are not associated with the '>>' symbol. A new message would normally not require such a notation; a forwarded message is typically shown differently, often accompanied by a specific indication such as "Fwd:"; and an urgent message would usually be marked with a different tag or flag to convey its urgency rather than a quoting symbol.
