Sonja buys a tropical bird from Ramon's rare bird store. Sonja asks Ramon about the bird's origins, and Ramon tells her, "It is from the rainforests of Brazil, and it is extremely rare." Sonja asks Ramon if the bird is on the endangered species list, but even though he knows that the bird is on the list, he tells her that it is not. When government officials come and take her bird away, Sonja is told that she has illegally purchased a bird that is on the endangered species list. In order to recover the price of the bird and the fines levied against her for buying an illegal bird, Sonja can file a lawsuit against Ramon for:
a. mistake.
b. negligence.
c. undue influence.
d. fraudulent misrepresentation.
