Solution
The correct option is A X-ray diffraction
Rosalind Franklin, a young biophysicist, was working on the structure of DNA around the same time as Watson and Crick. While they initially came up with a triple helical structure, she already had a strong clue that DNA is a double helix, through the images that she had developed through X-ray diffraction. Unfortunately, she wasn’t alive to share the Nobel Prize with them in the year 1962.
