[Beach Home] Wendy Hires Rob to Find and Negotiate a Price

[Beach Home] Wendy hires Rob to find and negotiate a price for her perfect vacation home. Rob previously helped Wendy find a home and Wendy was very satisfied with his service. Wendy had many demands for her dream vacation home and told Rob that each demand was nonnegotiable. Wendy desired her home to have five bedrooms, seven bathrooms, a large master suite with a balcony, a pool house, and she wanted the property to be within a block of the beach. Rob informed Wendy this was a high demand and he was not confident he could find a property that met all of Wendy's requirements within her price range. Wendy thought Rob was underestimating himself and told him that she was not willing to budge. Rob finds a home that meets all of her requirements, except it is five blocks from the beach. Rob informed the seller he was working on behalf of a principal and the property met all of her requirements. Rob negotiates an outstanding price and is excited to share it with Wendy. Rob tells Wendy about the stellar price and Wendy is devastated that the property is not in her defined location. She immediately calls the seller to rescind the offer but the seller declines, stating the offer is binding because as the seller knew, Rob had authority to contract and the seller was not aware of Wendy's requirements.
-Even though the home did not meet all of Wendy's requirements, what would have made Rob's offer authorized?

A) If Rob would have contacted Wendy and received her approval to extend an offer on a home that did not meet all of her requirements.
B) If Rob would have informed the seller of Wendy's name and contact information.
C) If Rob would have informed the seller the home did not meet all of the principal's requirements.
D) If Rob would have contacted Wendy and told her that he was going to make an offer on a home that did not meet all of her requirements.
E) Rob's offer was authorized.
