The correct answer is A

Explanation:

Answer 2

X-ray crystallography was a key technique used to explain the structure of DNA.

What is X-ray crystallography?

X-ray crystallography is used to obtain a 3D molecular structure from a crystal, in which the crystalline structure causes beam of incident X-rays to diffract into many specific directions.

Today mostly X-ray crystallography is used to obtain molecular structure of proteins and determines the function of residues.
