设在工程文件中有一个标准模块，其中定义了如下记录类型：
Type Books
Name As String*10
TelNum As String*20
End Type
在窗体上画一个名为Command1的命令按钮，要求当执行事件过程Command1_Click时，在顺序文件Person.txt中写入一条Books类型的记录。下列能够完成该操作的事件过程是

A．Private Sub Command1_Click()
Dim B As Books
Open "Person,txt" For Output As #1
B.Name=InputBox("输入姓名")
B.TelNum=InputBox("输入电话号码")
Write #1, B.Name, B.TelNum
close #1
End Sub

B．Private Sub Command1_Click()
Dim B As Books
Open "Person.txt" For Input As #1
B.Name=InputBox("输入姓名")
B.TelNum=InputBox("输入电话号码")
Print #1, B.Name, B.TelNum
Close #1
End Sub

C．Private Sub Command1_Click()
Dim B As Books
Open "Person.txt" For Output As #1
B.Name=InputBox("输入姓名")
B.TelNum=InputBox("输入电话号码")
Write #1, B
Close #1
End Sub

D．Private Sub Command1_Click()
Open "Person.txt" For Input As #1
Name=InputBox("输入姓名")
TelNum=InputBox("输入电话号码")
Print #1, Name, TelNum
Close #1
End Sub
