D Injures V's Leg and a Surgeon Advises Amputation

D injures V's leg and a surgeon advises amputation. V rejects the advice and dies.

A) D is not the legal cause of death because V's decision was independent and not reasonably foreseeable.
B) V's decision was a matter of chance and it would be unfair to blame D for her death on the basis of bad luck.
C) D is not the legal cause of death because this is an example of a 'victim escape' case in relation to which V's decision must be reasonable.
D) It is the policy of the law that those who use violence on other people must take their victims as they find them.
