Hi LoganTRK,

Check this example. Now please take its reference and correct your code.

Controller

public class HomeController : Controller
{
    // GET: /Home/
    public ActionResult Index()
    {
        List<SelectListItem> li = new List<SelectListItem>();
        li.Add(new SelectListItem { Text = "Select", Value = "0" });
        li.Add(new SelectListItem { Text = "A", Value = "1" });
        li.Add(new SelectListItem { Text = "B", Value = "2" });

        ViewData["country"] = li;
        return View();
    }
    [HttpPost]
    public ActionResult Country(string country)
    {
        if (country == "0")
        {
            return View();
        }
        else if (country == "1")
        {
            return RedirectToAction("Option", "AS");
        }
        else if (country == "2")
        {
            return RedirectToAction("Option", "AP");
        }

        return View();
    }
}

View

<div>
    <%using (Html.BeginForm("Country", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
        {%>
    <%:Html.DropDownList("country", ViewData["country"] as List<SelectListItem>)%>
    <input type="submit" value="GO" class="btn btn-info" />
    <% }%>
</div>
