Try the following, which passes the photo into the Form::file facade.

{!! Form::file('photo', $user_master->photo, ['class' => 'control-label input-sm', 'type'=>'file', 'accept'=>'image/*']) !!}

Instead of

{!! Form::file('photo', null, ['class' => 'control-label input-sm', 'type'=>'file', 'accept'=>'image/*']) !!}`

Here your answer contains a json string. Decode it before fetching any key. Try this :

foreach ($answers as $answer) {
    if(isset($answer['answer'])){
        $ans = json_decode($answer['answer'],true);
        if(is_array($ans)){
            quiz_que_ans_id=$ans['id']; 
        }
    }
}

The $answer['answer'] variable is a string comprising JSON encoded data; to access that, you need to decode it first:

$data = json_decode($answer['answer'], true);
$quiz_queue_ans_id = $data['id']; // work with decoded data
