Stockfish will give you that 24...Rxf2+, 24...Bxe4, 24....b5, and 24...Qc5 are all "winning" in the sense that the evaluation is better for Black. That is not the way the "correct" move is determined. The correct move is substantially better, by at least 3 points here, than the best of these alternatives.
You can always vote the puzzle with a thumbs down.
[Edit: Forgot the quotes around "winning". The correct move is determined by SF having gave a substantially higher eval than other alternatives, and, of course, the eval has to be in the player's favor whose move it was at the beginning of the puzzle.]
