Solution

The correct option is D Moseley's work on X-ray spectra
Henry Moseley observed regularities in the characteristic X-ray spectra of the elements by plotting square root of frequency of x-rays against atomic number which gave a straight line. Thereby he showed that the atomic number is the most fundamental property of elements rather than atomic mass.

Hence, option D is correct.
