How to extract an element from a Json Response in Jquery

I have an ASP.Net MVC Application and I got a

response from the server using this code segment.

public JsonResult GetVehicleByID(string VehicleID)
db.Configuration.ProxyCreationEnabled = false;

var res = from type in db.Vehicles
where type.ID == VehicleID
select new
ID = type.ID,
RegNo = type.RegNo
return Json(res, JsonRequestBehavior.AllowGet);

The code above returns the following
(Google Postman)

"ID": "000001",
"Type": "Internal"

I handled the response using following jQuery Ajax

function GetVehicle(id) {
async: true,
url: "GetVehicleByID?VehicleID=" + id,
cache: false,
dataType: "json",
contentType: "application/json",
success: function (data) {

//Parsing Method 1
//var a = jQuery.parseJSON(data);

//Parsing Method 2
var b = $.parseJSON(data);

I was unable to extract the
element from this response. There are several similar questions in the Stack Overflow & solutions of those questions are about parsing. I tried to parse in 2 ways but the browser log gives following error

Uncaught SyntaxError: Unexpected token o in JSON at position 1

Helping is highly appreciated than flagging this question as duplicate.

Try just console.log(data[0].Type). I believe jQuery is already parsing the response as JSON for you because you specified dataType: "json" and the response from the server had the right Content-Type header.
