Answer:
C) Implied warranty of fitness for a particular purpose.
Step-by-step explanation:
An implied warranty of fitness for a particular purpose refers to a warranty implied by law that if a seller is informed and got to know the specific purpose for which a good is being bought, the seller is giving a guarantee that the good fit for that specific purpose.
Since Sadie informed the salesperson of the purpose for which she was buying the shoes, the salesperson has breached the implied warranty of fitness for a particular purpose because Sadie bought the shoes based on his recommendation.
