Choice "C" is correct. A composition of creditors is an agreement between a debtor and at least two creditors that the creditors will take less than full payment to discharge the debts owed by the debtor to the creditors who participate in the composition agreement. The agreement results in discharge of the debts in full because a contract is created by the cross-promises of the parties (i.e., the cross-promises serve as consideration, so the pre-existing duty rule is avoided). On the other hand, an assignment for the benefit of creditors is a transfer of some or all of a debtor's property to a trustee who then uses the property to pay the creditors. There is no discharge of debts here because the creditors have not entered into any contract to take less than full payment.
