Answer:
b. Bob will lose because as a threshold issue Kelly had no legal duty to rescue him
Step-by-step explanation:
Legal duty refers to the practice of following and abiding by laws and regulations such as driving safe and not breaching the speed limit, keeping the environment around safe and not act in any way which shall disrupt it's safety.
In the given case, Bob himself acted negligently while ignoring the safety guidelines mentioned. Thus, Kelly cannot be held liable since she is under no legal duty to rescue a drowning person. Such non performance on her part does not make her liable and thus, Bob will lose the suit.
