(C) According to Chargaff's rule,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 $(C)$.Given that the percentage of thymine $(T)$ is $20\%$,then the percentage of adenine $(A)$ is also $20\%$.The total percentage of $A + T$ is $20\% + 20\% = 40\%$.Since the total percentage of all four bases $(A + T + G + C)$ is $100\%$,the sum of $G + C$ is $100\% - 40\% = 60\%$.Since the amount of guanine $(G)$ is equal to the amount of cytosine $(C)$,the percentage of guanine is $60\% / 2 = 30\%$.

If the percentage of thymine in $DNA$ is $20\%$,what will be the percentage of guanine (in $\%$)?
