***Just checking my answer on this one, as there is a conflict with the official answer.

Let X be the price of stuff. The price has just gone up to 107/100*x. In order for the price to be x again, we need to buy 100/107 of it. In terms of percentage change, this is 1-100/107 or 7/107 or 700/107%.

The correct answer is A.
