Raja Set Up a Web Site Selling Tee Shirts Decorated

Raja set up a web site selling tee shirts decorated with original artwork. The web site was marketed under a name very similar to a well- known professional basketball team. Raja had never heard of the team nor had he meant to fool anyone or to infringe anyone's trademark. One day, Liz went to Raja's site and bought a number of tee shirts with her credit card. Thinking that she was getting fan apparel from her favorite ball team, Liz was quite surprised and disappointed when she saw the merchandise that she received in the mail. What should she claim in order to get her money back?

A) undue influence
B) mistaken identity
C) frustration
D) duress
E) non est factum
