Passing 2 parameters but only 1 from sql server DB

Question

Is it possible to pass 2 parameters in web application but only 1 parameter comes from sql server db? The other parameter comes from a pre set dropdownlist. If it's possible, how to do it? This is what I have in mind but not sure if it is correct.

public static List<CompulsoryTable> GetCompulsoryCoverage(string vehicleType, string Option)
       {
           List<CompulsoryTable> getVehicleType = new List<CompulsoryTable>();
           using (SqlConnection con = DBConnection.GetDbCon())
           {
               SqlCommand cmd = new SqlCommand("select * from tblCompulsoryTable where VehicleType = @VehicleType", con);
               cmd.CommandType = CommandType.Text;
               cmd.Parameters.AddWithValue("@VehicleType", vehicleType);
               cmd.Parameters.AddWithValue("@CompulsoryOptions", Option);
               con.Open();

               SqlDataReader rdr = cmd.ExecuteReader();
               while (rdr.Read())
               {
                   CompulsoryTable Vehicles = new CompulsoryTable();
                   Vehicles.VehicleType = rdr["VehicleType"].ToString();
                   getVehicleType.Add(Vehicles);
               }
           }
           return getVehicleType;
       }
