Valerie the veterinarian accidentally left the door to her clinic open, and Dogbert, one of her patients, escaped. Dogbert ran down the road, through an industrial worksite, and ended up in a vacant field. He was found and returned to the clinic within an hour, completely unharmed. Is Valerie liable to Dogbert's owner for negligence?

Group of answer choices

a. No, because while it appears that Valerie did breach her duty of care, Dogbert suffered no injury while he was free, so no damages will be awarded.

b. Yes, because Valerie Vet breached a duty of care to her patient.

c. Yes, because allowing a dog to run loose for half an hour constitutes gross negligence, Valerie will be liable for punitive damages.

d. Yes, because it is foreseeable that an unleashed dog will run out of an open door, so Valerie will be liable for compensatory damages.
