Firstly, let's create a View Model to hold these things:

public class PlanViewModel
{
    public List Plans { get; set; }
}

Then, in your controller action let's build the Model:

public ActionResult Index()
{
    var model = new PlanViewModel();

    model.Plans = db.Plan_S
        .Select(p => new SelectListItem
        {
            Value = p.Hours,
            Text = p.PlanNames
        })
        .ToList();

        return View(model);
    }

Then in your View, do:

@model Pivot.Models.Plan_S
@{
    ViewBag.Title = "Index";
}

Index
   
    @Html.DropDownList("PlanNames", Model.Plans, "--select--")
    

Then you'll need to do the following in jQuery:
