Solution

A.      If West leads an honour, North wins and leads a heart, South winning as cheaply as possible.  Declarer exits on a diamond to East, who is endplayed.  A middle heart is best, but declarer can win and either throw East back in with a heart or simply run the Q round to East, win the club return, ruff a club with the 4 and play A and 5, keeping the 2 to throw under East's 3 so that North gets the K and an established club.

B.      If West leads a low diamond, North plays the 10, East winning and returning the suit.  North wins and leads a heart, South winning as cheaply as possible.  Now declarer must run the Q round to East, who returns the suit to North's §A.  South ruffs a club with the 4 and exits to East on the 5.

1.       If East returns a heart, perhaps cashing the A first, South (in either case) wins as cheaply as possible, cashes the top heart, and exits again to East on the 2, carefully preserved as in A.  Thus North makes the K and an established club.

2.       If East plays A and another spade, North wins and South ruffs a spade with the 2.  East's last three cards are all trumps, so that player has to ruff the diamond exit and give declarer another trump finesse at trick 12.
