You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
You create a Button control for the application.
You need to ensure that the application meets the following requirements:
* When the mouse pointer is over the Button control, the background color of the button is set to red and the Button control appears bigger.
* When the mouse pointer is not over the Button control, the button returns to its original state.
What should you do?

A.
Create a template. Declare a VisualState element in the template.

B.
Create a StoryBoard animation. Add an EventTrigger class to the Button control that begins the StoryBoard animation.

C.
Create a ScaleTransform class. Bind the ScaleX and ScaleY properties of the Button control to the Background property by using a custom value converter.

D.
Add a method named ChangeAppearance in the code-behind file. Subscribe the ChangeAppearance method to the MouseEnter event of the Button control.
