I am using one label and one checkbox but it showing single label and checkbox ,but label and checkbox should generate dynamically depending upon the question's option.

What I have tried:

private void SetAnswer()
        {
            StrQuery = "SELECT AnswerID,Answer FROM TBL_Answer where QuestionID='" + QID + "'";
            oDt = ClsConnection.ExecuteSelectQry(StrQuery);
            for (int i = 0;i< oDt.Rows.Count; i++)
            {
                //if (oDt.Rows.Count > 0)
                {
                    Label lbl = new Label();
                    LblAnswer.Text = oDt.Rows[i]["Answer"].ToString();

Your code is simply updating the label and checkbox you have on the page, so each iteration of the loop overwrites the last. There is nothing in your code that is creating new controls for each row. The easiest way to do this is to use a Repeater and bind your data to the repeater, then in the ItemTemplate of the Repeater you put your label and checkbox and bind them to the data for that row. If you google asp:Repeater you'll find lots of examples.

Solution 2

Use checkbox list  
<asp:CheckBoxList ID="chkAns" runat="server">
</asp:CheckBoxList>

and code behind

ListItem item = new ListItem();
item.Text = oDt.Rows[i]["Answer"].ToString();
 item.Value = oDt.Rows[i]["AnswerID"].ToString();
 chkAns.Items.Add(item);
