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);
