HISTORY:Took the X-Ray crystallography photographs that revealed that DNA is a Double Helix
A
Rosalind Franklin
B
Linnus Pauling
C
Fredrick Griffeth
D
Martha Chase
Explanation: 

Detailed explanation-1: -In addition, to publishing twenty-one papers on carbon structures and nineteen papers on viruses, Franklin is most well known for her discovery of the double helix that makes up DNA and the five publications she authored with her student, R.G. Gosling, on DNA structure (NIH).

Detailed explanation-2: -Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.

Detailed explanation-3: -British scientist Rosalind Franklin’s application of radiation science was truly historic. Her work with x-ray crystallography confirmed the double-helix structure of the DNA molecule.

Detailed explanation-4: -Rosalind Franklin’s X-ray diffraction patterns of DNA molecules rendered the important clue that DNA has the structure of a double helix.
