The correct answer is (c). A garnishee is a person who owes money to a judgment debtor. The judgment creditor can serve a garnishment order on the garnishee, which requires the garnishee to pay the money owed to the judgment debtor to the judgment creditor instead.
(a) A creditor’s debtor is a person who owes money to a creditor. This is not the same as a garnishee, because a garnishee is a person who owes money to a judgment debtor, not a creditor.
(b) A debtor’s debtor is a person who owes money to a debtor. This is not the same as a garnishee, because a garnishee is a person who owes money to a judgment debtor, not a debtor.
(d) None of the above is the correct answer.
