Which Statement Best Describes Short-Term Financing

Which statement best describes short-term financing?

A) 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 the use of short-term debt would probably increase the firm's risk.
B) Conservative firms generally use no short-term debt and thus have zero current liabilities.
C) 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.
D) If a firm that can borrow from its bank 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.
