Which statement best describes working capital financing policy?

a$.$Net working capital may be defined as current assets minus current liabilities, and an increase in the current ratio automatically indicates that net working capital has increased.

b$.$Although short$-$term interest rates have historically averaged less than long$-$term rates, the heavy use of short$-$term debt is considered to be an aggressive strategy because of the inherent risks of using short$-$term financing.

c$.$If a company follows a policy of $$matching maturities,$$ this means that it matches its use of common shares with its use of long$-$term debt as opposed to short$-$term debt.
