C is corrent because when Muldowney raised the amount to $800, he created the defense of material alteration. This is a personal defense to the extent of the original tenor of the instrument ($80) and a real defense to the extent of the alteration ($720). Therefore Lester, who qualifies as a holder in due course, is entitled to collect $80 from Wilbur. Lester must collect the remaining $720 from Muldowney, the party that materially altered the instrument.
A is incorrect because even in the face of a material alteration, Wilbur is still liable according to the original tenor of the note ($80).
B is incorrect because Wilbur’s defense is a personal defense only to the extent of the original value of the note ($80). Wilbur has a real defense on the remaining portion of the amounts ($720).
D is incorrect because the concept of "wrongful dishonor" excludes any permitted or justified dishonor by the bank such as when the drawer has insufficient funds in his account.
