Answer:
A) γ-rays
Explanation:
A gamma ray is described as a penetrating electromagnetic radiation that arises from the radioactive decay of atomic nuclei. The spectrum of the electromagnetic waves often stretch over an infinite range of wavelengths. The wavelengths range from 10-12m to upto 106 m. Whereas the least wavelength being of gamma rays tanges from 10-10 m to 10-14 m ( as y has the highest frequency).
Thus, out of the given four rays, the gamma rays ( γ-rays ) have the least wavelength.
