Answer:

D

Explanation:

In DNA, C and G always go together and A and T always go together so you simply take the first strand and replace each letter with its counterpart. Also for the numbers on the outside of the letters, you will simply swap them for the second strand. So since the first strand has 5' first and then 3', the second strand will have 3' first and then 5'.
