How do you handle this dealer screw-up?

Situation: live game at a friend's regular tourney. 4 players left in the game. The dealer folds pre-flop. Flop comes up 10/4/2 (rainbow, no flush possibility in these hands so I'm leaving the suits out). Player A goes all in w/$26K in chips. Player B calls. Player C calls.

Turn card is a 7. Player B goes all in with an additional $19K in chips.

This is an important hand in the game. Someone's going out, possibly two people and the rest will be in the money for the game. Action is on Player C and dealer _shows the river prematurely_ -- it's a 3. Tourney organizer says that we'll muck the 3 and flip the next card instead. Player C decides to go all in at this point.

Player A reveals 10/8 (one pair)
Player B reveals 10/4 (two pair)
Player C reveals 10/A

New river is an Ace. Player C now has the higher two pair.

Player B throws a fit. Player C feels guilty. Tourney organizer then decides that the 3 was the "true river" and all it did was give player C more information, declares Player B should get the pot.

My question is: how *should* this have been handled (assume the tourney organizer didn't say anything)??? I can see a few options: a) go with the river as it stands b) go with the next card in the deck c) shuffle the three back into the deck and re-deal the river...

c) shuffle the three back into the deck and re-deal the river...

That is the correct one. Leaving the mucked cards aside, the river that was prematurely exposed should be added to the remaining stub which is reshuffled and the top card dealt as a new river card.
