Given a MIDP 2.0 device supports alpha blending, a MIDlet needs to render semi-transparent images of size 10x10 pixels. However, these images need to be generated at runtime. That is, they CANNOT be loaded as PNGs. What is the correct way to create a 10x10, red, semi-transparent image, using only the MIDP 2.0 API? 

A. use createImage() to create a mutable Image; first fill it with white pixels, then fill it with red pixels 

B. This is not possible. An Image with semi-transparency CANNOT be created at runtime. 

C. use createImage() to create a mutable Image, then fill it with red pixels 

D. use createRGBImage() to create an immutable Image from ARGB data with the desired values 

Answer: D
