As can be seen in RAML, POST expects input in application/json format which eliminates two of the options as two options are in xml format.

Now out of the two remainingoptions, one has id field in request which is only mentioned for get response and not for POST request. Hence id field is not expected in POST request.

Hence correct answer is

{

"name": "GoerdiLa Forge",

"address": "1 Westland CA",

"customer_since":"2014-01-04",

"balance": "4829.29",

"bank_agend_id": "12556"

}
