Reference - Accidental Sale

Reference - Accidental Sale. ABC Motors ordinarily deals in used cars and also does some amount of repair work. Robby entrusted his automobile to ABC Motors to have the oil changed and get new brakes. The car was parked in the lot along with other cars, some of which were for sale. The manager of ABC Motors accidentally sold the car to Connie because she saw it and took it upon herself to offer a good price. The manager was attempting to increase the shop's profit margin. Connie had no idea that the car did not belong to ABC Motors. When Robby went to pick up the car, he was very upset that it was gone. The manager told Robby that he was very sorry, but that he was not negligent and only made an honest mistake. According to the manager, Robby accepted the risk of this type of loss; and his only recourse was against Connie. Which of the following is true regarding Connie's rights to the car?

B) Connie can keep the car without paying any additional amounts only because she paid cash for it.
C) Connie can keep the car without paying any additional amounts, and whether or not she paid cash makes no difference.
D) Connie must give the car to Robby.
E) Connie must return the car to the repair shop.
