A FRICTIONLESS ICE RINK!!!!! HAHAHAHAHAHAHAHA!!!
Anyway, now that I'm done laughing, the answer is C because all actions have an equal and opposite reaction, so when she throws it back, she will be propelled with the same force that she threw it with, backwards.

C. She gets the momentum of the frisbee by catching it, and then imparts momentum in the other direction back to the toy. If she tosses the frisbee at the same velocity it had when she caught it, she now has double the momentum the frisbee originally had.

C, momentum is transfered to the skater when she catches it and then more momentum is transfered when she throws it back. Both these transfers are in the same direction to the skater so she will end up moving faster (away from her friend) in C than in the other options.

Assuming she throws it with the same hardness she received it, they are all the same
