a. x - ray diffraction
b. ultraviolet spectroscopy
c. radioactive labeling
d. paper chromatography

Explanation:

Rosalind Franklin's work on DNA structure relied on X-ray diffraction, which produced the famous Photo 51, providing critical data about DNA's helical, three-dimensional form. The other techniques listed are not associated with her key contributions to DNA structure discovery.

Answer:

A. X-ray diffraction
