You use Microsoft .NET Framework 4 to create a Windows Forms client application.
You write the following code segment.
sealed class FormSettings : ApplicationSettingsBase {
[UserScopedSetting()]
[DefaultSettingValue(“225, 200”)]
public Size FormSize
{
get { return (Size)this[“FormSize”]; }
set { this[“FormSize”] = value; }
}
}
The application contains a form of type Form1 that contains a FormSettings object named frmSettings1.
You need to maintain the user’s form size preference each time the user executes the application.
Which code segment should you use?

A.
private void Form1_Load(object sender, EventArgs e)
{
frmSettings1.Reset();
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e) { frmSettings1.FormSize =
this.Size;
frmSettings1.Save(); }

B.
private void Form1_Load(object sender, EventArgs e)
{
frmSettings1.Reset();
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{ frmSettings1.FormSize = this.Size;
frmSettings1.Upgrade(); }

C.
private void Form1_Load(object sender, EventArgs e) { this.Size = frmSettings1.FormSize;
} private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{ frmSettings1.FormSize = this.Size;
frmSettings1.Upgrade(); }

D.
private void Form1_Load(object sender, EventArgs e)
{
this.Size = frmSettings1.FormSize;
} private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{ frmSettings1.FormSize = this.Size;
frmSettings1.Save(); }
