In your controller:

function index()
    {
        //store your post form data into an array 
         $arrData = array();
         $arrData["qA"]     = $this->input->post("qAfieldName");
         $arrData["qB"]     = $this->input->post("qBfieldName");
         $arrData["qC"]     = $this->input->post("qCfieldName");
         $arrData["question"]     =  $this->input->post("questionfieldName");
         $this->load->model('survay');
         //pass data array into model          
         $survay_data = $this->survay->dosurvay($arrData);
    }

And in model:

    function dosurvay($arrData){        
        $this->db->select('QID, Question, qA, qB, qC');
        $this->db->from('tblquestions');
        $this->db->where('Question', arrData['Question']);
        $this->db->where('qA', $arrData['qA']);
        $this->db->where('qB', $arrData['qB']);
        $this->db->where('qC', $arrData['qC']);
        $this -> db -> limit(1);

............other stuff
}

This is the line that is giving you problems, because you haven't initialized the variables:

$survay_data = $this->survay->dosurvay($Question, $qA, $qB, $qC);

The variables $Question, $qA, $qB, $qC haven not been passed to the function or initilized anywhere in your code.

You need to define the variables they you are sending to the function:

$question = 'How are you?';
$qA = 'qA';
$qB = 'qB';
$qC = 'qC';

In addition to this, you're passing an array with 1 element to your view: $viewData['survay_data']. This variable contains an array of the variables you are looking for. Rather, just do something like this:

$viewData = $survay_data;

You also need to put your view name in quotes:

$this->load->view('survay_view', $viewData);
