Use this code as per my knowledge you can add HTML tag using literal.You can do this by :

    StringBuilder strHTML1 = new StringBuilder();
    strHTML1.Append("<select>");
    strHTML1.Append("<Option value = 'volvo'>Volvo</Option>");
    strHTML1.Append("<Option value = 'saab'>Saab</Option>");
    strHTML1.Append("<Option value = 'mercedes'>Mercedes</Option>");
    strHTML1.Append("<Option value = 'audi'>Audi</Option>");
    strHTML1.Append("</select>");

and final code is :

  strHTML1.Append("<table align=center cellpadding='0' cellspacing='0' width='100%'>");
  strHTML1.Append("<tr>");
  strHTML1.Append("<td>");
  strHTML1.Append("Passenger");
  strHTML1.Append("</td>");
  strHTML1.Append("</tr>");
  strHTML1.Append("<tr>");
  strHTML1.Append("<td>");
  strHTML1.Append("<select>");
  strHTML1.Append("<Option value = 'volvo'>Volvo</Option>");
  strHTML1.Append("<Option value = 'saab'>Saab</Option>");
  strHTML1.Append("<Option value = 'mercedes'>Mercedes</Option>");
  strHTML1.Append("<Option value = 'audi'>Audi</Option>");
  strHTML1.Append("</select>");
  strHTML1.Append("</td>");
  strHTML1.Append("</tr>");
  strHTML1.Append("</table>");
