Step-by-step explanation:
The question is asking which of the given options is an example of unsecured debt. Unsecured debt refers to a loan or debt that is not backed by collateral. In this case, the answer is d) credit card debt. Unlike secured debts, which are tied to assets like property or cars, unsecured debts are granted based on the borrower's creditworthiness without any collateral.
A zero-coupon bond is a type of bond that doesn’t pay interest or coupon payments, but it is typically backed by the issuer's credit rather than collateral, making it technically unsecured but not in the conventional sense as credit card debt. An indenture is a legal and binding contract between bond issuers and bondholders, defining the obligations and responsibilities of each party, but it is not a type of debt per se. Therefore, credit card debt is the correct answer as it is a common form of unsecured debt.
