consulting or IB because these 2 tracks have always been the only tracks justifying the cost of these MBAs. A Stanford B-school professor did extensive research 20 years ago to show that. The situation may have changed a little over recent years with the tech industry warping the picture.
If your child gets tired of consulting and doesn't want to get into IB post-MBA, why Wharton? That's the place for Consulting and IB! If s/he is interested in entrepreneurship or some untraditional tracks, M or S would be the best bet--just a bet!
