The table below shows the region of electromagnetic spectrum of different waves,

Region of electromagnetic spectrum
Infrared waves	Radio waves	Gamma rays
X-rays	Visible light	Ultraviolet waves

The table given above shows the list of some electromagnetic waves. If arranged in order of their wavelengths from shortest to longest then gamma ray would be the first in the list. Gamma rays have the shortest wavelength of the electromagnetic spectrum. Its wavelength is less than 100 picometers.

Conclusion:

Hence, the correct answer is (c) gamma ray.
