How to read this JSON?

Im sorry if this is a newbie question but I'm getting confuse about how to read this json string:

{
    "VF001JV018":[
      {
         "kode_question":"VF001JV018",
         "kode_option":1,
         "kode_option_tipe":"PF006",
         "nama_option":"Pilihan 1",
         "reference_db":null,
         "reference_table":null,
         "reference_field":null,
         "required_value":0,
         "reference_pk":null,
         "status":1
      },
      {
         "kode_question":"VF001JV018",

      }
   ],
   "VF001JV020":[
      {
         "kode_question":"VF001JV020",
         "kode_option":1,
         "kode_option_tipe":"PF001",
         "nama_option":"Kode Toko",
         "reference_db":"crm",
         "reference_table":"customer",
         "reference_field":"kode_customer",
         "required_value":0,
         "reference_pk":"          ",
         "status":1
      }
   ]
}

How to show the data in list? for example:

<ul>
<li><strong>VF001JV018</strong></li>
<li>VF001JV018-1</li>
<li>VF001JV018-4</li>
<li>VF001JV018-5</li>
<li><strong>VF001JV020</strong></li>
<li>VF001JV020-1</li>
</ul>

I use jquery each function to loop each element but still no luck

$.getJSON('data.json', null, function(response){
    var echo = '<ul>';
    $(response).each(function(k,v){
        echo += '<li><strong>'+k+'</strong> : '+v+'</li>';
    });
    echo += '</ul>';
    $('#here').html(echo);
});

response is not a HTML string or DOM element. You cannot pass it to jQuery this way.

Use jQuery.each to loop over it:

$.each(response, function(k, v) {
    echo += '<li><strong>'+k+'</strong></li>';
});

You cannot concatenate the string with v, as v is an array again. You have to loop over it and access the specific information you want to print, e.g. v[i].status.
