While Brad is walking to work, he trips and hits his head. He begins to bleed profusely. Dia, a local doctor, is walking by when this happens. She tells Brad his head wound is serious and that he needs immediate treatment, and she offers to fix his wound for him on the spot for $200. Without waiting for Brad to respond to her advice, she begins to treat the wound. After she's done, the doctor leaves Brad with a bill for $200 for the cost of her supplies. Will a court require Brad to pay the $200?

Probably no, because Dia did not formally offer her services

Probably yes, because the parties formed a contract

Probably no, because Brad did not accept Dia's offer

Probably yes, because the parties formed a quasi-contract
