What is a key feature of asset-backed securities that distinguishes them from other securities?

Asset-backed securities are unique because they are tied to specific assets, which serves as collateral backing the value of the securities. This means that the cash flows from the asset pool—icons like mortgages, car loans, or credit card debt—are used to pay interest and principal to investors. The linkage to tangible assets provides investors with a level of security that is distinct from many other types of securities, where the backing may not be as clearly defined or may rely on the issuer's creditworthiness alone.

While other options present characteristics of different types of securities, the defining feature of asset-backed securities is their connection to specific pools of assets, making them attractive to investors looking for both yield and a certain degree of protection based on the underlying collateral.
