Solution

The correct option is A X-rays
  • Physical mutagens. Ionizing radiations such as X-rays, gamma rays and alpha particles cause DNA breakage and other damages.
  • Infra-red, visible and radio waves have longer wavelength and hence carry leser energy and cannot cause mutation.

So, the correct answer is 'X-rays'.
