Based on what I've got, i guess the answer is A. However, I'm not quite sure of myself.
From what I can see coil Y has its own magnetic field because current is flowing in that coil. When there's a flow of current there will be a magnetic field around it. Thus, placing coil Y close to coil X will produce induced e.m.f on coil X.
The main problem here is how to determine the direction of current flow in coil X ?
well, please correct me if my theory was incorrect
