IEnumerable <SelectListItem> - Condition for each item in IEnumerable

I'm using MVC Razor's @Html.DropDownList to generate dropdown list.

        IEnumerable<SelectListItem> cSfRR = db.TABLE.Where(m => m.cRoleName == dbrole)
        .Select(c => new SelectListItem
         {
             Value = c.ID,
             Text = c.Name 
         });
        ViewBag.cSfRR = cSfRR;

This TABLE has one more field which determines activity of each item in the table.

If I use following code I get that activity field included after c.Name

        IEnumerable<SelectListItem> cSfRR = db.TABLE.Where(m => m.cRoleName == dbrole)
        .Select(c => new SelectListItem
         {
             Value = c.ID,
             Text = c.Name + " - " + c.Activity 
         });
        ViewBag.cSfRR = cSfRR;

My problem is that that field has only one character which determines it's activity. A - Active, N - Not active. I would like to show custom text "Not Active" for those items in SelectListItem that have value "N". Something like...

        IEnumerable<SelectListItem> cSfRR = db.TABLE.Where(m => m.cRoleName == dbrole)
        .Select(c => new SelectListItem
         {
             Value = c.ID,
             Text = c.Name + " - " + IF C.ACTIVITY IS "N", THEN PRINT "NOT ACTIVE" 
         });
        ViewBag.cSfRR = cSfRR;

I hope someone can help me achieve something like this

DROPDOWN LIST ITEM 1

DROPDOWN LIST ITEM 2

DROPDOWN LIST ITEM 3

DROPDOWN LIST ITEM 4

DROPDOWN LIST ITEM 5 - NOT ACTIVE

DROPDOWN LIST ITEM 6 - NOT ACTIVE

DROPDOWN LIST ITEM 7 - NOT ACTIVE

You could try something like this:

IEnumerable<SelectListItem> cSfRR = db.TABLE.Where(m => m.cRoleName == dbrole)
            .Select(c => new SelectListItem
             {
                 Value = c.ID,
                 Text = c.Name + (c.Activity == "N") ? " - Not Active " : "";
             });
            ViewBag.cSfRR = cSfRR;

You can use conditional operator - ?: Operator 

IEnumerable<SelectListItem> cSfRR = db.TABLE.Where(m => m.cRoleName == dbrole)
.Select(c => new SelectListItem
{
    Value = c.ID,
    Text = c.Name + (c.Activity == "N" ? " - NOT ACTIVE" : "")
});
ViewBag.cSfRR = cSfRR;

I don't promote the use of ViewBag, but this should work:

IEnumerable<SelectListItem> cSfRR = db.TABLE.Where(m => m.cRoleName == dbrole)
    .Select(c => new SelectListItem
     {
         Value = c.ID,
         Text = c.Name + (c.ACTIVITY == "N" ? " - NOT ACTIVE" : string.empty)
     });
    ViewBag.cSfRR = cSfRR;
