D Correct answer
Explanation

In the electromagnetic spectrum, X-rays have higher frequency and energy than visible light, infrared, radio waves, and microwaves, but lower energy than gamma rays. Compared to infrared, X-rays have shorter wavelength and higher energy. Option A is wrong because X-rays have longer wavelength than gamma rays. Option B is wrong because X-rays have shorter wavelength, not longer. Option C is wrong because X-rays have much shorter wavelength than radio waves.
