Final answer:
The Payment System Board ensures the payment system contributes to economic efficiency, competition, and stability of the financial system, which supports a stable and efficient national financial infrastructure.
Step-by-step explanation:
The Payment System Board plays a crucial role in ensuring that the payments system contributes to three primary goals: economic efficiency, competition, and the stability of the financial system. By doing so, the Payment System Board underpins a financial infrastructure that enables goods and services to be exchanged for money or other financial assets in an efficient and competitive market. This, in turn, supports a stable national financial system as outlined by the Federal Reserve. Furthermore, it helps protect individuals' savings and maintains the integrity of the financial system, particularly during economic downturns, as was evident during the 2008-2009 financial crisis. Therefore, Option 2 is the answer: Economic efficiency, competition, and stability of the financial system are the aspects the Payment System Board ensures the payments system contributes to.
