Defence by Declining a Capture
For the cost of a Rook (Rd1), White spots an opportunity to win 2x Black Pieces -- Bishop (Bd5) and Knight (Nf6) -- with White's Queen (Qc5) completing the trade, on d5, resulting in a clear material gain.
Why should White's Rd1 decline the opportunity to capture Black's Bd5, which would begin the aforementioned material swap?
