[单项选择题] 有如下函数过程。

Function Fun( By Val x As Integer,By Val y As Integer) As Integer

Do While y ＜＞ 0

reminder = x Mod y

xmy

y = reminder

Loop

Fun = x

End Function

以下调用函数的事件过程，该程序的运行结果是

Private Sub CommandT_Click( )

Dim a As Integer,b As Integer

a = 100:b =25

x =Fun(a,B)

Print x

End Sub

A．0

B．25

C．50

D．100
