Answer:
b. not get her money back since she has affirmed the contract by taking an unduly long time to disaffirm.
Step-by-step explanation:
Since she had already used the ring for a long time, she wont be able to get her money returned because she had already afformed the contract by using the ring for a long time and depreciating it. She should´ve returned it as soon as she knew it wasn´t authentic and she wanted her money back, eventhough they didn´t take a contract nor a receipt, with this kind of non written agreements the code of honour applies and since the seller didn´t have any by selling a ring with lies.
