SOLUTION

The correct answer is beta rays.

Cosmic rays even they dont lie in an electromagnetic spectrum are electronegative. They have high-energy charged particles that travels through space at nearly speed of light. Their extremely high energies are compared to those of gama rays at the upper end of electromagnetic spectrum.

While beta rays are not electromagnetic. They are just fast moving electrons rather.
