Peter made a contract with Ann under which Ann was to sell Peter's goods on commission from January $1$ to June $30.$ Ann made satisfactory sales up to May $15$ and was about to close an unusually large order. Peter suddenly and without prior notice revoked Ann's authority to sell. Can Ann continue to sell Peter's Goods during the unexpired term of her contract?

No$,$ because the principal revoked authority.

No$,$ because the contract was not within the statute of frauds.

Yes, because she had made satisfactory sales.
