The electromagnetic spectrum arranged by wavelength from longest to shortest is:
- **Radio waves** (longest wavelength)
- **Infrared radiations**
- **X-rays** (shortest wavelength)
Thus, the correct order in decreasing wavelength is:
B. Radio waves > infrared radiations > X-rays**

GVMRIX increasing order of wavelength
XIRMVG decreasing order of wavelength
so the answer is D
