Json Data extraction

I have a webservice and it returns json data like this..

{"d":"{\"RES\":[],\"STAT\":\"FAIL\",\"SID\":\"0\"}"}

how i can i read the STAT=FAIL from this. I wrote service in c#.

my script is

$.ajax({
    type: "POST",
    url: "http://localhost/EMRDMSService/Service.asmx/User_Login",
    data: "{lg:" + JSON.stringify(GetLogDet) + "}",
    // url: "http://localhost/EMRDMSService/Service.asmx/Permission_List",
    // data: "{userid:" + JSON.stringify(GetLogDet) + "}",

    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (r) {          
        console.log(r.d.STAT);
    }
});

But the r.d.STAT is undefined? Can anybody help me with this?

As said in some of the comments, {"d":"{\"RES\":[],\"STAT\":\"FAIL\",\"SID\":\"0\"}"} isn't correct JSON. However, if you can't update the webservice, you could try this in your success callback:

var d = JSON.parse(r.d);
console.log(d.STAT);

EDIT in response to OP edits r.d.STAT will be undefined because d is interpreted as a String, not a Object. That's why you'll have to parse it or update the webservice to remove the quotes around the value of d.
