【加试题】阶乘是基斯顿﹒卡曼于1808年发明的运算符号。正整数n的阶乘为n！=1×2×3…×n。小王编写了如下VB程序用来求S=1！+2！+3！+…+10！。

  Function fac(n As Integer) As Long

    fac = 1

    For i = 1 To n

fac = fac * i

    Next i

End Function

Private Sub Command1Click()

Dim s  As Long, j As Integer

For j = 1 To 10

Next

Text1.Text = Str(s)

End Sub

 方框中的正确语句是：（   ）

A、s = s + fac(j)

B、s = fac(j)

C、s = s + i * fac(i)

D、s = s + fac(i)
