Solution
The correct option is B Gamma rays
Cosmic rays are high-energy particles that bombard the earth. These particles the "primary" cosmic rays are mostly protons, but also can be heavier nuclei or electrons. When the primary cosmic rays collide with atoms in the atmosphere, they produce showers of particles called "secondary" cosmic rays. These secondaries are mostly neutral and charged pions. The neutral pions decay into pairs of gamma rays, which may create an electron and a positron.
So, we can say that gamma rays in Electromagnetic Spectrum are present in cosmic radiation.
