The correct answer is (D) X-rays.

Electromagnetic radiation is ordered by wavelength and frequency in the electromagnetic spectrum. The spectrum, from longest wavelength (lowest frequency) to shortest wavelength (highest frequency), includes Radio waves, Microwaves, Infra-red, Visible light, Ultraviolet, X-rays, and Gamma rays. Among the given options, X-rays have the shortest wavelength.

Visible light occupies a small portion of the spectrum, with wavelengths typically ranging from about 400 nm (violet) to 700 nm (red). Infra-red radiation has longer wavelengths than visible light, and Microwaves have even longer wavelengths. X-rays have much shorter wavelengths, typically ranging from 0.01 nm to 10 nm.
