Please review this scenario again:

Andre offered to sell to Brianna a personal watercraft that was not running very well for $500. Brianna was interested but not willing to pay $500. She said, "I'll give you $400." Andre said that he would think about it. Later, the same day, Andre asked Charlotte if she would be interested in purchasing the personal watercraft for $500. Charlotte said, "Would you consider $450?" Andre said he would think on it. A few minutes later, Dylan who had heard that Andre wanted to sell the watercraft accepted Andre's offer to sell for $500, and they agreed that he would pick up the watercraft the next day. A few minutes later, Brianna called saying that she accepted Andre's offer to sell the watercraft for $500. A few minutes after that, Charlotte called and told that she accepted his offer to sell the watercraft for $500. Andre told Brianna and Charlotte that he had already sold it, and they are angry, threatening to sue. Additionally, through no fault of anyone, there was a fire at Andre's home that night and the personal watercraft burned. Dylan was not happy. A dispute ensues regarding what obligations Andre has, if any.

What was the status of the negotiations between Charlotte and Andre immediately prior to the fire?

Charlotte cannot accept Andre's offer because she did not do so in her initial conversation with Andre.

Charlotte did not reject Andre's offer because she merely made an inquiry.

Charlotte cannot accept Andre's offer because he already sold the personal watercraft, and that terminated the offer to her.

Charlotte rejected Andre's offer by making a counteroffer.
