Rod Wanted to Buy $25 000 Worth of Mandolins from Maggie

Rod wanted to buy $25 000 worth of mandolins from Maggie, but there was a potential problem with payment.Although he did not have immediate access to the full price, Rod explained that he would be able to make monthly payments of $2500 by re-selling the mandolins in his music shop.Maggie was inclined to accept those payment terms, but she was worried that if the economy experienced a downturn, Rod would find it difficult, month after month, to meet his obligations.The parties therefore agreed to a compromise: Rod would immediately deliver a negotiable instrument that entitled Maggie to (a) monthly payments of $2500 plus interest, and (b) the full amount of the outstanding balance if Rod failed to make a monthly payment.That negotiable instrument can best be described as

A) a bill of exchange with a lump sum clause.
B) a certified cheque with balance in default clause.
C) a bill of exchange with a fast-track clause.
D) a promissory note with a notice of dishonor.
E) a promissory note with an acceleration clause.
