Which MEL expression demonstrates dot notation to access fields of the payload?

• A. #[Payload]
• B. #[Message]
• C. #[Message.Payload.Field]
• D. #[Message.Payload]

Answer: (D)

In MEL, you use dot notation to reach into nested parts of the message. To get a specific piece inside the payload, you start with the Message, then move to Payload, and then access the desired field with another dot. The expression that does this is #[Message.Payload.Field], which drills into the payload and returns the value of that particular field inside it. The other forms either stop at the payload itself, return the whole message, or just expose the payload object without drilling into a subfield, so they don’t demonstrate accessing a specific field within the payload.
