Solution
The correct option is C Astbury and Franklin
William Astbury, a British scientist, obtained the first X-ray diffraction pattern of DNA. X-ray diffraction patterns of crystallized molecules can reveal their structures with atomic precision. Rosalind Franklin's X-ray diffraction patterns of DNA molecules rendered the important clue that DNA has the structure of a double helix. Hence the correct answer is (C)
