Electromagnetic Spectrum

In order of increasing frequency, the ranges of the electromagnetic wave spectrum are : Gamma Rays $\rightarrow$ X-Ray $\rightarrow$ Ultraviolet radiation $\rightarrow$ Visible Light $\rightarrow$ Infrared radiation $\rightarrow$ Microwaves $\rightarrow$ Radio and TV waves .

So the correct option is Gamma Rays

Gamma Ray's are made from supernova they come from 2 form short and long. Long Gamma Ray's last 1 minute, and short last for a few seconds. Every day NASA found 1 gamal Ray per day

Gamma Rays $\rightarrow$ X-rays $\rightarrow$ Ultraviolet Rays $\rightarrow$ Infrared Rays $\rightarrow$ Microwaves $\rightarrow$ Radio Waves
In the electromagnetic spectrum, Gamma Rays have the highest frequency and the lowest wavelength.

It is Gamma Rays because Gamma rays are em waves of very high frequency and of high penetrating power. So gamma rays are powerful. ... Gamma rays are high-energy photons (about 10 000 times as much energy as the visible photons), The same photons as the photons forming the visible range of the electromagnetic spectrum – light.
