小金仔细分析该程序段后，发现其中缺少了(   )

For i = 5 To 4 Step -1

        k = i

        For j = 6 - i To 1 Step -1

           If a(j) < a(k) Then k = j

        Next j

        If i <> k Then

           t = a(i): a(i) = a(k): a(k) = t

        End If

    Next i

数组元素a(1)到a(5)的值依次为“41，66，70，83，31”，经过该程序段“加工”后，数组元素a(1)到a(5)的值依次为（  ）

Do While i <= n

x = Int(Rnd() * 9) + 1 If x Mod 2 = 1 Then

a(i) = x Else

a(n) = x n = n - 1

End If

i = i + 1 Loop

数组元素的初值均为 0，执行该程序段后，在下列选项中 a(1)至 a(5)各元素值不可能的是（  ）
