Something like this should do the trick, if the ViewBag item is a boolean:

<option id="Custom1" value="Custom1" @(ViewBag.SomeBoolean ? "selected" : string.Empty)>Custom1</option>

It's worth noting, however, that this is very often more readily accomplished by binding the view to a model and setting that property on the model. Then you can make use of the HTML helpers, such as @Html.CheckBoxFor() and @Html.CheckBox(). The code you're showing indicates that you probably have logic in a controller which belongs in a model.
