A tenant rented a two-story building; she operated a store on the first floor of the building and lived on the second floor. During a winter weekend when the tenant was out of town and the store was closed, a thief broke into the building. The thief left the building exposed to the elements. As a consequence, water in the pipes froze and burst the pipes, resulting in structural damage to the building. When the tenant returned and discovered the problem, she promptly notified the landlord. The lease contains a provision obligating the tenant to maintain and repair the premises during the tenancy. Which of the following would be the tenant's best argument that she is not obligated to repair the damage to the building?

A. The criminal act of a third party caused the damage.
B. The lease was residential.
C. The structure of the building was damaged.
D. The damage was due to natural causes.
