有如下程序段：
tail = 6：i = 1：r = Val(Text1.Text)
Do While i < r
For j = tail To i + 1 Step -1
If a(j) > a(j - 1) Then
t = a(j): a(j) = a(j - 1): a(j - 1) = t
End If
Next j
i = i + 1
For j = i To tail - 1
If a(j) < a(j + 1) Then
t = a(j): a(j) = a(j + 1): a(j + 1) = t
End If
Next j
tail = tail - 1
Loop
数组元素a(1)到a(6)的值依次为“73、56、28、61、44、92”，若在文本框Text1中输入“2”，则经过该程序段“加工”后，数组元素a(1)到a(6)的值依次为

A．73,61,56,92,44,28	B．92,73,56,61,44,28
C．92,73,61,56,28,44	D．92,73,61,56,44,28
