【加试题】有如下程序段：

   Const n = 6

   Dim a(1 To n) As Integer

   Dim i As Integer, j As Integer, t As Integer

   Do While True

For i=1 to n-1

      If a(i)>a(i+1) then Exit For

Next i

     If i < n Then

       For i = 1 To n

        j = Int(Rnd * 6) + 1

        t = a(j): a(j) = a(i): a(i) = t

       Next i

     Else

       Exit Do

     End If

   Loop

数组中a(1)到a(6)的值依次为“56，34，48，87，65，96”，经上述程序段执行后a(1)到a(6)的值依次为（  ）

A、96 87 65 56 48 34

B、34 48 56 65 87 96 

C、选项A和B都有可能

D、选项A和B都不可能
