The image depicts Rosalind Franklin's x-ray diffraction image of DNA. How did this evidence contribute to the understanding of DNA's structure?

• It helped to confirm the double helix structure of DNA.

• It was used to identify the genetic code.

• It was used to prove the law of segregation.

• It was used to demonstrate that DNA is the genetic material.
