Well. . . it really depends on what the court knows.
B didn't know the bag was poisoned and C is dead, so only A knows A tried to kill C, which means he'd likely blame B for cutting the bag. Now, B would probably blame A for cutting the bag because only A and B really know who did it, which would end in a stalemate at a court. Knowing this, it would be best if A and B agreed to blame C for cutting his own bag by accident. Of course, either A or B might back out of the agreement, telling the court know that a conspiracy was taking place, making it possible that both get blamed, so they would probably just blame each other and nobody would be convicted.
Or, they would simply not tell anybody so nobody would get blamed. By the time the body was found, there wouldn't be any evidence to prove he was with them at the time he died, and if people knew he left with them they could just say he got lost and they never found him. Alternately, they could tell the police upon arrival that he got lost so it wouldn't be suspicious when they found a corpse lying in the desert.
If the court knows A poisoned the bag and B cut the bag, B could possibly say he cut the bag so C couldn't drink the poisoned water. He could furthermore say he didn't just tell C the bag was poisoned because he was dehydrated and not thinking clearly. A would get attempted murder and B would either get off the hook or get negligent homocide. If the court also knows why B cut the bag, the murder should fall on B, and A should get attempted murder only.
If I put a bomb in someone's house and cause it to detonate 5 minutes after he's supposed to get home, but that person dies in a car accident on the way home, I will not be blamed for his death, though I will get in a lot of trouble for trying. Likewise, A would not be blamed for C's death, even if A had already set the stage to kill him.
Of course, this does depend on the local laws.
