Diamond.

Answer: 1 -
Trump. This dummy calls for passivity. Partner's discouraging heart warns against another heart play (declarer likely has the jack). Any minor-suit switch is dangerous. As you can see from the full deal below, a trump switch gives nothing away. Declarer will fail by at least a trick.
