  Explanation/Reference:

  Option 3 is the only corect answer as it concatenates payload with String.

  Below option wont work.

  #["The payload is " ++ payload]

  Concatenation function expects both arguments to be string. As the question says payload is json object , this will throw error while running it. You can try this in Anypoint Studio and you will get the same result which I mentioned.

  hence correct answer is

  The payload is: #[payload]
