Assume that a self-employed plumber has two immediate needs in his business: (1) he needs cash badly but his liabilities are already maxed out, and (2) he needs to reduce the level of his accounts receivable on the balance sheet. The plumber could achieve both of these objectives simultaneously by:

a. obtaining an unsecured loan.

b. selling receivables to a factor.

c. assigning receivables as collateral for a loan.

d. securing credit with a blanket inventory lien.

e. None of the above.
