Question:You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
You create a page that contains the following code fragment:

<asp:ListBox ID="lstLanguages" AutoPostBack="true" runat="server" />

You write the following code segment in the code-behind file for the page:

void BindData(object sender, EventArgs e) {
 lstLanguages.DataSource = CultureInfo.GetCultures(CultureTypes.AllCultures);
 lstLanguages.DataTextField = "EnglishName";
 lstLanguages.DataBind();
}
You need to ensure that the lstLanguages ListBox control maintains the selection of the user during postback.
Which line of code should you insert in the constructor of the page? 

A this.Init += new EventHandler(BindData); 
B this.PreRender += new EventHandler(BindData); 
C lstLanguages.PreRender += new EventHandler(BindData); 
D lstLanguages.SelectedIndexChanged += new EventHandler(BindData);
