Kathy, a fashion model, witnessed a motor vehicle accident but did not stop because she was late for her pedicure and simply didn't want to get involved. Had she stopped, she could have saved the life of Tom, who was thrown from the car and landed in a water-filled ditch, without danger to herself. When Tom's widow hears that Kathy could have easily saved Tom's life but chose to ignore the situation, she sues Kathy. The state has no "Good Samaritan" laws or duty-to-assist laws, but such cases have been brought in the past. Which of the following will the court apply when making a decision in this case?

A) administrative law
B) statutory law
C) common law
D) equity law
