Choice "B" is correct. The drawer of a draft is secondarily liable. The drawer is liable only after the draft is presented to the drawee, the draft is dishonored, and the drawer is given notice of dishonor.
Choice "c" is incorrect because an acceptor is primarily liable. When a drawee signs a draft, the drawee becomes an acceptor and is primarily liable.
Choice "d" is incorrect because with a cashier’s check, the bank is both the drawer and the drawee. As the issuer the bank would be primarily liable.
Choice "a" is incorrect because the maker of a note is primarily liable.
