Warren brought his television in for repairs. After Warren left the store, gunmen came in to rob the proprietor. As they ran out, Warren's television was knocked over and destroyed. Warren demanded that the proprietor of the store compensate him for the fair market value of the television. The bailee:
 A) is liable, since the goods were not returned to Warren in proper condition.
 B) is liable, since the bailee did not prevent the gunmen from damaging the television.
 C) is not liable, since this was a mutual-benefit bailment.
 D) is not liable, since the damage was caused by the criminal act of a third party.
