Sierra offers to sell Alyssa a Scottish terrier puppy for $800. Alyssa and Sierra do not discuss the dog's ancestry, but Alyssa believes that the dog came from champion lines and agrees to the price. Alyssa later discovers that the puppy is worth only $200. Can Alyssa rescind the contract based on her mistake?
a. Yes, because the dog was clearly not worth $800.
b. Yes, because Alyssa had a duty to investigate, which she failed to perform.
c. Probably not, because Alyssa made a mistake about the dog's value, not a mistake about a material fact.
d. Probably so, because Alyssa made a mistake about a material fact.
