C is corrent. Stop payment orders may be oral and are valid for 14 days. Written stop payment orders are valid for 6 months and are renewable.
A is incorrect because the bank is liable only if its failure ultimately causes its customer a loss. If the drawer has no valid defense to refuse payment, the drawer has suffered no loss. The bank must also be given a reasonable time to act on the stop payment order.
B is incorrect because the drawer may give the bank a stop payment order and the drawer will eventually have to pay if s/he has no valid defense to payment.
D is incorrect because stop payment orders may be oral.
