I was stuck between the 2 but I guess this is one of the classic questions which pop on CR. It isn't about selecting the better option, but about selecting the best option.
I have a slight disagreement with Vivian's logic though. Except questions to weaken do not mean that the answer choice always strengthens the argument. It could also be that the answer choice is neutral (as long as the answer choice does not weaken the argument).
In this case, though we have an answer choice that strengthens the argument.
