Remove the Only Defender
Black's queen is the only thing standing between White's rook and the back rank.
Your Move
White to move. Find the move that wins the queen outright.
Solution: 1. Nxd7
The queen on d7 is completely undefended — Black's king is too far away and the pawns can't reach it. Nxd7 simply wins the queen for free, and it was the only piece keeping the d-file and back rank under control.
