In order to determine acid strength, we need to look at the stability of the conjugate base. The weaker the conjugate base, the stronger the acid. In this case, the conjugate base of D will be the most stable because it is the most electronegative, so it will attract the negative charge the best. Therefore, D will be the weakest acid and A will be the strongest acid. The order will be D < A < C < B. The only choice that shows this order is choice D.
