A. Dim objStream As IsolatedStorageFileStreamobjStream = New
    IsolatedStorageFileStream( _
    "Settings.dat", FileMode.Open)Dim result As String = New
    StreamReader(objStream).ReadToEnd

B. Dim objFile As IsolatedStorageFileobjFile =
    IsolatedStorageFile.GetMachineStoreForAssemblyDim objStream As
    IsolatedStorageFileStreamobjStream = New IsolatedStorageFileStream( _
    "Settings.dat", FileMode.Open, objFile)Dim result As String = New
    StreamReader(objStream).ReadToEnd

C. Dim objStream As IsolatedStorageFileStreamobjStream = New
    IsolatedStorageFileStream( _
    "Settings.dat", FileMode.Open)Dim result As String objStream.toString

D. Dim objFile As IsolatedStorageFileobjFile =
    IsolatedStorageFile.GetMachineStoreForAssemblyDim objStream As
    IsolatedStorageFileStreamobjStream = New IsolatedStorageFileStream( _
    "Settings.dat", FileMode.Open, objFile)Dim result As String = objStream.ToString

Answer: B
