Caleb Is Stabbed by Zachariah During a Barroom Brawl

Caleb is stabbed by Zachariah during a barroom brawl. The injury is serious but not life-threatening. During surgery at the hospital where there is medical malpractice, Caleb dies. Caleb's family files wrongful death suits against Zachariah, the hospital, and the doctor. Zachariah's most successful defense will probably be:

A) That Caleb consented to the attack.
B) That Zachariah's action was not the proximate cause of Caleb'sdeath and that the doctor's intervening actions removed liability from him.
C) That the doctor has more money than Zachariah and the one with deeper pockets should be held solely liable.
D) That Caleb was known to be a troublemaker.
E) All of the above.
