(b) The requirement is to identify the working capital
technique that increases the payable float. Answer (b) is the
correct answer because payment by draft (e.g., a check) is slower
than other methods of payment such as electronic cash transfers.
Answers (a) and (d) are incorrect because they are techniques
designed to speed the processing of cash receipts. Answer (c) is
incorrect because EDI involves processing transactions electronically.
This would speed up the payment of payables.
