Which of the following statements is CORRECT?

a. A short-term loan can usually be obtained more quickly than a long-term loan, but the cost of short-term debt is normally higher than that of long-term debt.

b. Under normal conditions, a firm's expected ROE would probably be higher if it financed with short-term rather than with long-term debt, but using short-term debt would probably increase the firm's risk.

c. If a firm that can borrow from its bank at a 6% interest rate buys materials on terms of 2/10, net 30, and if it must pay by Day 30 or else be cut off, then we would expect to see zero accounts payable on its balance sheet.

d. Conservative firms generally use no short-term debt and thus have zero current liabilities.

e. If one of your firm's customers is "stretching" its accounts payable, this may be a nuisance but it will not have an adverse financial impact on your firm if the customer periodically pays off its entire balance.
