[Yard Mowing] Sophie Agreed to Mow Reza's Yard Once a Week

Multiple Choice

[Yard Mowing] Sophie agreed to mow Reza's yard once a week for $50 per week throughout the summer. Sophie, however, was having trouble getting her money from Reza. On one occasion, he in handwriting gave her an IOU saying "I, Reza Salehi, owe Sophie Smith $50." A couple of weeks later, Reza did not have the money to pay Sophie what he owed her, and he handwrote the following on a piece of paper and gave it to her: "I, Reza Salehi, promise to pay Sophie Smith or to bearer, the sum of $100 on Monday, July 22, 2016." Sophie quit mowing Reza's yard; and, disgusted with Reza, Sophie assigned both documents to Vince. When Vince presented the documents to Reza, Reza refused to pay on the basis that after inspecting the yard, he decided that Sophie was doing a poor job. Vince told him the documents constituted negotiable instruments, but Reza pointed out that he had not signed the documents with his signature at the end.
-What is the effect of the instruments being written by hand?

A) Handwriting does not prevent the instruments from being considered negotiable only because neither Sophie nor Reza would be considered merchants in the transactions at issue.
B) Handwriting does not prevent the instruments from being considered negotiable only because Reza would not be considered a merchant in the transaction at issue, and Sophie's status as a merchant is irrelevant.
C) Handwriting does not prevent the instrument from being considered negotiable only because Sophie would not be considered a merchant in the transaction at issue, and Reza's status as a merchant is irrelevant.
D) Handwriting does not prevent the IOU instrument from being negotiable, but it does prevent the other instrument from being negotiable.
E) The issue of the instruments being handwritten does not prevent either from being considered negotiable.
