3. C, a neighbour of D, wished to borrow a sum of money from a local bank. D was quite wealthy but elderly, with very poor eye sight. He frequently requested C to read his newspaper to him when C would drop by for a visit because reading was exceedingly difficult for him. One evening, C. placed a paper before D and explained to him that he wished to borrow a sum of money but required a letter of reference before the bank would make the loan. He requested D to sign to the paper to satisfy this requirement. D trusted his friend C, and signed the paper at his request without reading it. Unknown to D, the paper was a guarantee of C's indebtedness, and not a letter of reference, and C later defaulted on his debt. a. D may successfully plead non est factum as a defence to any claim by C's creditor b. If C had told D that the paper was a guarantee for $1,500 when it was in fact $2,000, D could still successfully plead non est factum as a defence c. C required D's signature on the paper because the Statute of Frauds requires a guarantee to be in writing and signed to be enforceable I d. a and c e. All of these
