b

Explanation:

Recall the wavelength ranges of different electromagnetic - waves. X - rays have wavelengths in the range of approximately 0.01 - 10 nm, which corresponds to region B. Radio waves have long wavelengths, from about 1 m to 100 m, corresponding to region D. Gamma rays have very short wavelengths, around 0.0001 - 0.01 nm, corresponding to region A. Infrared has wavelengths from about 700 nm to 1 cm, corresponding to region C.

Answer:

X - rays: B
Radio Waves: D
Gamma Rays: A
Infrared: C
