(B) According to Chargaff's rules for double-stranded $DNA$,the amount of adenine $(A)$ is equal to the amount of thymine $(T)$,and the amount of guanine $(G)$ is equal to the amount of cytosine $(C)$.Since $A = T$ and $G = C$,the total amount of purines $(A + G)$ is equal to the total amount of pyrimidines $(T + C)$.Therefore,the ratio of purines to pyrimidines is $\frac{A + G}{T + C} = 1$.
