Isis Used a Municipal Parking Lot to Park Her Car

Isis used a municipal parking lot to park her car in an American city. She used an electronic lock to lock her car and kept the keys in her wallet. On returning, she noticed the word "angels" scratched on her car door. Isis spent $200 in repairing the damage. Isis's boyfriend suggested that she sue the city because it was the city's responsibility to prevent vandalism. In this situation, _____.

A) a bailment was not created and, therefore, it was not the city's duty to protect Isis's automobile
B) a bailment was created solely for Isis's benefit and, therefore, the city only owed minimal care in protecting Isis's car
C) a bailment was created solely for the benefit of the city and, therefore, the city should have exercised ordinary care in preventing vandalism of Isis's car
D) a bailment was created for the mutual benefit of Isis and the city and, therefore, both parties were responsible for protecting the car from vandalism
