D Correct answer
Explanation

Erwin Chargaff discovered that in DNA, the amount of adenine equals thymine (A=T) and guanine equals cytosine (G=C), known as Chargaff's rules. This base pairing was crucial for Watson and Crick to deduce the double helix structure. Watson and Crick built on this discovery.
