You are developing a utility screen for a new client application.

You are developing a utility screen for a new client application. The utility screen displays a
thermometer that conveys the current status of processes being carried out by the application.
You need to draw a rectangle on the screen to serve as the background of the thermometer as
shown in the exhibit. The rectangle must be filled with gradient shading.
Which code segment should you choose?

Exhibit:
  

A. Rectangle rectangle = new Rectangle(10, 10, 450, 25); LinearGradientBrush
    rectangleBrush =
    new LinearGradientBrush(rectangle, Color.AliceBlue,
    Color.CornflowerBlue,
    LinearGradientMode.ForwardDiagonal); Pen rectanglePen = new Pen(rectangleBrush);
    Graphics g = this.CreateGraphics(); g.DrawRectangle(rectanglePen, rectangle);
B. Rectangle rectangle = new Rectangle(10, 10, 450, 25); LinearGradientBrush
    rectangleBrush =
    new LinearGradientBrush(rectangle, Color.AliceBlue,
    Color.CornflowerBlue,
    LinearGradientMode.ForwardDiagonal); Pen rectanglePen = new Pen(rectangleBrush);
    Graphics g = this.CreateGraphics(); g.FillRectangle(rectangleBrush, rectangle);
C. RectangleF rectangle = new RectangleF(10f, 10f, 450f, 25f); Point[] points = new
    Point[] {new Point(0, 0),
    new Point(110, 145)}; LinearGradientBrush rectangelBrush =
    new LinearGradientBrush(rectangle, Color.AliceBlue,
    Color.CornflowerBlue,
    LinearGradientMode.ForwardDiagonal); Pen rectanglePen = new Pen(rectangleBrush);
    Graphics g = this.CreateGraphics(); g.DrawPolygon(rectanglePen, points);
D. RectangleF rectangle = new RectangleF(10f, 10f, 450f, 25f); SolidBrush
    rectangleBrush =
    new SolidBrush(Color.AliceBlue); Pen rectanglePen = new Pen(rectangleBrush);
    Graphics g = this.CreateGraphics(); g.DrawRectangle(rectangleBrush, rectangle);
