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 control:

<asp:Calendar EnableViewState="false" ID="calBegin" runat="server" />

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

void LoadDate(object sender, EventArgs e) {
 if (IsPostBack) {
  calBegin.SelectedDate = (DateTime)ViewState["date"];
 }
}
void SaveDate(object sender, EventArgs e) {
 ViewState["date"] = calBegin.SelectedDate;
}

You need to ensure that the calBegin Calendar control maintains the selected date.
Which code segment should you insert in the constructor of the page? 

A this.Load += new EventHandler(LoadDate);
this.Unload += new EventHandler(SaveDate); 

B this.Init += new EventHandler(LoadDate);
this.Unload += new EventHandler(SaveDate); 

C this.Init += new EventHandler(LoadDate);
this.PreRender += new EventHandler(SaveDate); 

D this.Load += new EventHandler(LoadDate);
this.PreRender += new EventHandler(SaveDate);
