  <p>The White queen is under attack, yet one shall not rush and capture it. The White may fork the Black king and queen and then fork two rooks:</p>

  After 1...Rxd5 2.cxd5, *both queens are attacked*. They either both get captured, or (if black moves his to safety) neither is. So black lost the exchange.
  
  After 1...Qxd5 2.cxd5 Nxe2, white has lost a knight.
  
  Cxd5 seems the better capture to me on general grounds (repairs white structure a bit, makes pawn c5 weaker) but that's far less important than the full rook difference between 1...Rxd5 and 1...Qxd5.
