有程序段如下：

Dim a(1 To 8) As Integer

K = 8: n = 8

For i = 1 To 3

    For j = i + 1 To n

        If a(i) < a(j) Then

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

        End If

    Next j

    For j = n - i To i + 1 Step -1

        If a(k) > a(j) Then

            t = a(k): a(k) = a(j): a(j) = t

        End If

    Next j

    k = k - 1

Next i

数组元素a(1)~a(8)中的初始值为：8,13,7,14,6,9,5,12,执行该程序段后，数组元素a(1)~a(8)中的值将变为（     ）

A、14,13,12,8,9,7,6,5

B、5,6,7,9,8,12,13,14

C、5,6,7,8,9,12,13,14

D、14,13,12,9,8,7,6,5
