Correct option is D
The good defences to an action in tort are: • Act of God (A): An unforeseeable event or natural disaster that is beyond human control. • Volenti non fit injuria (B): The principle that a person who knowingly and voluntarily exposes themselves to risk cannot claim for injury. • Private defence (C): The defence used to protect oneself or others from harm. Trustee do son tort (D) is not a good defence in tort as trustees cannot be held liable for the wrongs of others.
