Betty Bower, an adult, asked Jeff Geetus to lend her $1,000. Geetus replied that he would do so only if Bower's father, Cash, would guarantee the loan. At Bower's request, Cash mailed a signed letter to Geetus: "If you lend $1,000 to my daughter, I will repay it if she doesn't." On September 15, Geetus, having read Cash's letter, lent $1,000 to Bower, which Bower agreed to repay in installments of $100 plus accrued interest on the last day of each month beginning October 31. Cash died on September 16. Later that same day, unaware of Cash's death, Geetus mailed a letter to Cash advising that he had made the $1,000 loan to Bower on September 15. Bower did not pay the installments due on October 31, November 30, or December 31, and has informed Geetus that she will be unable to make repayments in the foreseeable future. For this question only, assume that Bower's entire $1,000 debt is due and that she has failed to repay any part of it. In an action by Geetus against Cash's estate for $1,000 plus accrued interest, which of the following, if any, will serve as (an) effective defense(s) for Cash's estate? I. There was no consideration to support Cash's promise, because he did not receive any benefit. II. Cash died before Geetus accepted his offer. III. Cash died before Geetus notified him that his offer had been accepted. 
I only. II only. I and III only. Neither I nor II nor III.
