Solution

The correct option is D 16.3% T and 34.1% C
The purine adenine (A) always pairs with the pyrimidine thymine (T) and the pyrimidine cytosine (C) always pairs with the purine guanine (G). These base pair relationships are often called Chargaff's rules of DNA base pairing.
As, A = T and C = G, hence answer is '16.3% T and 34.1% C'
