You can use asp:radiobuttonlist control for the same and by using rblistId.SelectedValue you can fetch the selected value

Hi,
In your case follow this.

C#

string strAnswr= string.Empty;
if(opt1.Checked)
{
    strAnswr = opt1.Text;
}
else if(opt2.Checked)
{
    strAnswr = opt2.Text;
}
else if(opt3.Checked)
{
    strAnswr = opt3.Text;
}
else
{
    strAnswr = opt4.Text;
}

It can be more simple if you bind it with RadioButtonList.

ASP

//suppose you have
<asp:radiobuttonlist id="RadioButtonList1" runat="server" xmlns:asp="#unknown">
</asp:radiobuttonlist>

C#

string strAnswr= RadioButtonList1.SelectedItem.Text; // simple

Hope it helps you.
Thanks.

One way you can do it following way

in aspx page i used yours markup with additional text property

XML

<asp:RadioButton ID="opt1" runat="server" Text="opt1 radioButton selected" GroupName="a"/>
     <asp:RadioButton ID="opt2" runat="server" Text="opt2 radioButton selected" GroupName="a" />
     <asp:RadioButton ID="opt3" runat="server" Text="opt3 radioButton selected" GroupName="a" />
     <asp:RadioButton ID="opt4" runat="server" Text="opt4 radioButton selected" GroupName="a" />
       <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />

in code being we can make out our selected text like below

C#

protected void Button1_Click(object sender, EventArgs e)
         {
             string checkedval="";
             if (opt1.Checked)
             { checkedval = opt1.Text; }
             else if (opt2.Checked)
             { checkedval = opt2.Text; }
             else if (opt3.Checked)
             { checkedval = opt3.Text; }
             else if (opt4.Checked)
             { checkedval = opt4.Text; }
             Response.Write(checkedval);

         }

Other way is to use radiobutton list

<asp:radiobuttonlist id="RadioButtonList1" runat="server" xmlns:asp="#unknown">
       <asp:listitem value="1">opt1</asp:listitem>
       <asp:listitem value="1">opt2</asp:listitem>
       <asp:listitem value="1">opt3</asp:listitem>
       <asp:listitem value="1">opt4</asp:listitem>
      </asp:radiobuttonlist>

C#

protected void Button1_Click(object sender, EventArgs e)
{
    string checkedval="";
    checkedval= RadioButtonList1.SelectedItem.Text;
    Response.Write(checkedval);
}
