A is corrent. The requirement is to identify the defense that generally may be used against all holders of a negotiable instrument. A is corrent because minority of the maker is a real defense that is assertable against any party.
B is incorrect because breach of warranty is a personal defense and only applies to the party who was subjected to the breach.
C is incorrect because lack of consideration is also a personal defense.
D is incorrect because fraud in the inducement is a personal defense and only applies to the party who was defrauded.
