I guess it would be the best to trim the values before passing the model to your view.
Nevertheless, this might help:

@Html.DropDownListFor(
  model =>
  model.bvODSMapping.Benefit_Set,
  Model.BenefitSet.Select(
    item => 
    new SelectListItem
    {   
      Selected = item.Selected, 
      Text = item.Text.Trim(), 
      Value = item.Value
    }),
  new { id = "BSet", style = "width:230px;" })
