Probably the Most Sensible Cash Management Policy Would Be to Maintain

Probably the most sensible cash management policy would be to maintain:

B) about 90 percent of the firm's ordinary cash needs in cash and delay payment on the remaining 10 percent.
C) enough cash on hand to meet any potential demand for cash.
D) a zero-cash balance and transfer funds semi-monthly to pay bills.
E) twice the amount of cash on hand that would be typically indicated based on the firm's normal cash flows.
