The answer can be presented in 5'-> 3' direction or 3'->5' direction.

It is up to you to discern the real answer.

In the case of this question, I just produced a 3'->5' RNA strand and then flipped it so that it will be a 5'->3' strand. I did this because all the answer choices are presented 5'->3'

examples : 5'-AAT-3' and 3'-TAA-5'
these two strands are the samething. Whether something is 5' or 3' direction is all relative, and depends on the direction you're viewing the phosphodiester bonds.
