option c is correct one

Explanation:

according to chargaff's rule ratio of  purine and pyrimidine are constant.the ratio will be 1:1.Here amount of guanine is equal to  to cytosine and the amount of adenine should be equal to thymine.

First rules is %A=%T AND %G=%C

in DNA adenine pair with thymine and guanine pair with cytosine.

so A+T/G+C=1 .It constant.
