A borrower owed a lender $$50,000$ due on March $1.$ On January $10,$ the lender telephoned the borrower and said that he would discharge the debt if the borrower would promise to pay the lender $$45,000$ by January $15.$ The borrower responded, $$I will attempt to get the money together.$$ On January $11,$ the lender again telephoned the borrower and said that he had changed his mind and would expect the borrower to make full payment on March $1.$ On January $15,$ the borrower tendered $$45,000$ as full payment, which the lender refused to accept. On March $1,$ the borrower refused the lender$$s demand for $$50,000,$ and the lender sued for that amount.$$

Which of the following statements best supports the lender$$s position?$$

Group of answer choices

The borrower$$s January $10$ statement was not a return promise, and therefore the lender effectively revoked his offer on January $11.$

The lender$$s offer to discharge the debt was a gift promise and therefore was not binding on the lender.

The January $10$ telephone conversation between the lender and the borrower created an executory accord and therefore did not operate as a discharge of the $$50,000$ debt.

The lender$$s promise to discharge the $$50,000$ debt was not enforceable because it was not in writing.
