An interview has two purposes: for them to find out if they want to hire you and for you to find out if you want to work there. The second half of that is often neglected or even forgotten entirely. The questions you are at the end are one of your prime opportunities to put them on the spot about whether you want to work for them.
I think the chances that you can ask a question that impresses them so much that you will change a "not hire" into a "hire" decision on their part is basically zero. The decision on whether to hire you or not will be made based on your CV and the earlier, employer-led, part of the interview, so there is little value in trying to come up with questions that will impress them, instead I suggest you use this as a valuable opportunity to ask about the company you may be joining. If they haven't shown you where you will be working, ask about that; if you'll be relocating, ask about the area and whether the company provides any help for finding a place, etc.; ask about their approach to programming, or the way the company structures the day, or child-care issues, or whatever it is that matters to you about a place you're going to work.
Good luck with the interview!
