"Substance G reacts with compound XY to form GY and X."

Explanation: A single replacement reaction has the form A + BC → AC + B (an element replaces another element in a compound). The other choices describe decomposition (XYZ → X + YZ), combustion (X burns in O2), and double replacement (QR + GT exchange ions).
