A. 17% A, 17% T, 33% G, 33% C

B. 29% A, 14% U, 11% G, 46% C

C. 4% A, 4% U, 46% G, 46% C

    D. 12% A, 12% T, 30% G, 46% C

    Explanation:

    Both option A and D could represent single strand DNA but since A has equal proportion of A and T/G

    C could also represent double stranded DNA.

    The best option here is option D.
